Partitioning Mac drive in a safe way

Among a slew of hardware components embedded in Mac, hard drive is an integral component that facilitates data storage. Based on the size of the hard drive, a massive amount of data can be stored to it. To avoid data untidiness, partitioning Mac drive is a wise decision, as it keeps your data protected against likely threats.

Partitioning Mac drive is a general issue, which becomes complicated when the user is not aware of the way it is done. More precisely, the one who does not know how to partition or repartition Mac drive may lose his data lost in case of repartitioning. However, you must admit that partitioning a hard drive on Mac is quite sophisticated as compared to that on Windows. In order to avoid data loss or a like situation, many of you do not even try partitioning your Mac drive and store all your data to the Mac boot volume (i.e. Macintosh HD). Since boot volume of your Mac drive contains system files (i.e. Mac OS X files and installed applications), it not safe to save your precious data to this volume.

At this point, some of the Mac users may ask that why it is not safe to save data to the boot volume? Well, storing data to the Mac boot volume is not in your favor, as you would not be able to access it if your Mac fails to boot. In such a situation, you cannot even opt for rebooting your Mac since it requires you to format the boot volume first. On the other hand, a hard drive having several volumes is far away from any such threat, as even Mac failure cannot affect your data at all.

Is partitioning Mac drive advantageous
Partitioning Mac drive is advantageous for you as well as for your Mac system; to know how, go through the following:

Suppose your Mac drive has only one partition (i.e. the boot volume, Macintosh HD) having all your data along with the system files stored on it. Besides, the secondary drive you have is partitioned into several volumes; one of these is the boot volume. Corruption of the boot volume of your Mac drive causes Mac data inaccessibility, whereas the same issue on the secondary drive does not affect the data stored on it at all, even if you format its boot volume to reinstall Mac OS X.

Besides, it must be known to you that partitioning Mac drive not only facilitates storing different types of data (such as pictures, videos, applications, and more) on separate Mac volumes, but also allows you to go for multi-boot. This means that you can install multiple operating systems (i.e. both Mac and Windows) on separate volumes of your Mac drive. Therefore, if you are using Mac OS X Lion and want Mountain Lion to be installed on a separate volume, partitioning Mac drive is what you need to go for. However, if you want a Windows operating system to be installed on a separate volume of your Mac drive, then you have to use Mac inbuilt Boot Camp Assistant tool for this. By having multiple operating systems installed on your Mac drive, you can access your data even if one of these fails to boot.

How to partition a new hard drive on Mac
You might be using a spare hard drive (internal or external, mainly external) to save the backup copies of all crucial files of yours. For this, instead of storing all data on a common partition as well as to avoid data untidiness, you should split this hard drive space into multiple partitions. Even though you must have a Mac partition manager app to get this done, you can also use Mac inbuilt Disk Utility as the default Mac disk partition manager.

For this, you need to follow the steps discussed underneath:
1. Hook up the secondary hard drive to your Mac.
2. When Disk Insertion message pops up, click Initialize button on it
(When you click Initialize button that is given on the Disk Insertion message box, Disk Utility is launched automatically)
3. In Disk Utility, select this drive at the left and go to the Erase tab at the right.
4. Herein, click Format dropdown menu and choose Mac OS Extended (Journaled).
5. Specify a Name for this disk, and then
6. Click Erase button to format this drive.
Once disk formatting is finished, continue with the following steps to partition it:
7. When this hard drive is selected at the left, go to the partition tab at the right
8. Click Options button and choose GUID Partition Table on your Intel-based Mac or Apple Partition Map on your PowerPC-based Mac, and then click OK button.
9.  After that, click Volume Scheme dropdown menu and select the number of partitions you want to have to this disk.
10. Select one volume in the graphical view of this hard drive and give it a Name, choose Mac OS Extended (Journaled) as its Format, and specify its Size beneath the Volume Information area
11. Now, repeat step no. 10 for other newly created volumes
12. When finished with the step no. 11, click Apply button to save these partitions

Based on both the size of the hard drive and the number of partitions to be created on it, time elapsed in saving these partitions may vary. Once these partitions are saved, a message pops up to notify the same to you. After that, you can also use any of these partitions to install Mac OS X.

On the other hand, if you need to repartition your Mac drive, you need to boot with a secondary bootable media (i.e. Boot Mac Lion or Mountain Lion with Recovery HD, and for earlier versions, boot with Mac OS X install disc). If you have free space available on your Mac drive, then you can use it to create a new volume. Otherwise, you will have to resize one or more other volumes to create free space.

In case, if you are not comfortable with Disk Utility to partition Mac drive, you can also use a Mac disk partition manager for the same. However, do not use any app without having its proper knowledge.

A Walk-Through of Resizing Mac OS X Partition

How many partitions your Mac drive is divided into? Well, in case you are going to reply this as only one, please hold on! You need to be attentive to partition your Mac drive instead of responding to any such question. Another question popping up in this situation is did you try partitioning your Mac drive? Well, you might not have tried partitioning it on your own (i.e. using Mac partition manager), but you need to go for it at the earliest. However, you may not find partitioning Mac drive quite trouble-free especially when it contains data and the system files saved on a single partition, as it may give some adverse results as well.

You might be thinking that why you are being compelled for partitioning you Mac drive while saving all data on a single partition makes it quite easy to be accessed. In fact, you are not being compelled, but suggested to partition your Mac drive into multiple partitions and store data on them, as saving data along with the system files on a common drive can be quite unfavorable for it. Even a minor glitch may cause corruption in one or more system files and hence, your Mac may not be able to boot further.

Despite avoiding the odds for corruption in files, Mac failure and hence, data loss, partitioning Mac drive not only makes data storage efficient, but keeps data easily accessible as well. In fact, based upon the requirements, one can partition his Mac drive into 16 partitions (max.). The one and only requirement for partitioning is a reliable partitioning tool in order to get it done efficiently. Well, you can also use Mac inbuilt Disk Utility as the Mac partitioning tool.

What Demands for Mac Drive Partitioning
Though partitioning Mac drive is not easy (especially when it contains data), still it is recommended to go for partitioning it because in spite of what all is mentioned earlier, it also facilitates installing multiple operating systems (i.e. Mac as well as Windows) on separate partitions of your Mac drive. In fact, following are the major advantages that you gain after partitioning your Mac drive:

For Easy, Simple, and Efficient Storage
Data storage becomes simple, better, or being precisely, it becomes quite efficient when you store different types of data (e.g. movies, pictures, audio and video songs, apps, and more) separately. For example, if you have a collection of movies that are stored on a separate partition of your Mac drive. In case you want to watch a movie, then you can open the particular partition (i.e. partition containing movies) and you do not have to search for a particular movie throughout in different partitions. Additionally, partitioning your Mac drive allows your keep your data arranged orderly.

For the Security of your Data
In spite of making data storage scheme efficient, partitioning Mac drive helps you keep your data secure against every single threat to the boot volume. Suppose, your Mac has only one partition (i.e. the one it boots from, Macintosh HD). In fact, it can also be termed as the un-partitioned drive. On this drive, there is no doubt that a slew of system file are stored, which keep undergo execution repeatedly as long as your Mac is running. Since even a single minor problem may cause it fails to boot, all your data becomes inaccessible in every adverse situation. Conversely, having multiple partitions not only allows you save data separate from the system files, but also install multiple operating systems on its separate partitions. This makes your Mac data always accessible to you.

Resizing the Boot Volume of your Mac Drive
As discussed earlier, in order for partitioning your Mac drive, all you need to have is a Mac partition manager. Since, Mac inbuilt Disk Utility facilitates formatting, partitioning, resizing, repairing, imaging, and cloning Mac disks. Your cam also uses Disk Utility for resizing the boot volume of your Mac drive. In this regard, you need to track the following steps:

Since the boot volume is the primary partition, you cannot make any changes on it when booted from it. Therefore, to resize this volume, you need to boot from a secondary bootable media. In fact, you can boot your Mac OS X Lion or Mountain Lion from Recovery HD, whereas for some earlier versions of Mac OS X (i.e. earlier than Mac OS 10.7 Lion) you need to have its bootable disc.

Booting from Recovery HD
Restart your Mac and hold down the Command + R keys or the Option key right after you hear Mac startup tone. When you see the grey screen, you can release these keys. Now, between Macintosh HD and Recovery HD, choose Recovery HD to boot from, and then launch Disk Utility in the Utilities window.

Booting from Mac OS X Boot Disc
For this, insert your Mac boot disc, and then restart your Mac. Make sure you press the C key tight after you hear Mac startup tone. As gray screen appears, release the C key. Now, in the Mac OS X boot window, select a preferred installation language and click the Next button. In Mac OS X Utilities screen, launch Disk Utility
Step1: In Disk Utility, select your Mac drive at the left and go to the Partition tab at the right
Step2: In the graphical view of the hard drive, select Mac boot volume by holding its bottom boundary (or the bottom-right corner) and drag it upwards to shrink it
Step3: In case you need to enlarge the boot volume using available free space, drag it downwards by holding its bottom boundary (or the bottom-right corner)
Step4: When done, click the Apply button to save the changes
After that, exit Disk Utility and other windows (if opened any), and then restart your Mac normally (i.e. in normal mode). However, make sure you eject the boot disc when booting normally. Once it boots to the desktop, you can verify the changes done.

Mac Partition Manager to Ease Creating, Deleting, and Modifying Mac Volumes

When it comes to partition your Mac drive, all you need to have is a professional Mac partitioning application that makes the steps involved in the process quite easy. Based on your requirements, you can partition your Mac drive into several volumes. In fact, Mac OS X facilitates formatting, deleting, and resizing (i.e. on an Intel-based Mac) existing Mac partitions as well. To get all these operations done efficiently on your Mac, you can use either Disk Utility or a professional Mac partition manager.

The hard drive embedded on your Mac provides massive amount of storage space that you can partition into a number of volumes of both equal and unequal sizes. In case your Mac has a number of partitions, you can save your precious data separate from the system files. This keeps all your data secure against every feasible threat to your Mac boot volume. In addition, following are the benefits of partitioning the Mac drive:

When your Mac has various volumes, you can store different types of data separately on these volumes. For example, you can store movies, images, videos, and songs on one volume, Mac apps and other system data on another volume, and professional documents and other related data on another volume.

Since a separate volume acts like a separate disk, you can multi boot your Mac (i.e. install multiple operating system on separate volumes of a single drive) system. Multi boot your Mac system allows installing not only Mac OS X, but Windows as well. Therefore, partitioning the hard drive is certainly a wise decision.

As you know that Mac OS X facilitates partitioning its hard drive both during and after its installation, in case you are going to partition Mac drive during Mac OS X installation, you need to format this drive first. Alternatively, you can directly partition your Mac drive and format these partitions as Mac OS Extended (journaled). At this point, you might be thinking that why you need to format your Mac drive before partitioning it. Well, formatting Mac drive enables it to be used by Mac for data read/write operations. After that, partitioning this drive on Mac is not that difficult. However, you must know how it is done. Since you need to have a professional Mac partitioning application, based on the partition manager you use, steps to partition a brand new hard drive on Mac are different. As for now, go through the following steps to partition a brand new drive on Mac using Disk Utility:

Initializing Mac Drive
When you install this hard drive on your Mac, Disk Insertion message pops up. Click Initialize button on this message box and it launches Disk Utility.

•    Select this hard drive in the left pane of Disk Utility
•    Go to the Erase tab in the right pane
•    In the Format dropdown menu, choose Mac OS Extended (Journaled) as the drive format
•    Specify a name for this drive in the Name field
•    Click Erase button to start formatting it

As you click Erase button, a message pops up; click Erase button on the message box.

Partitioning Mac Drive
After formatting this hard drive successfully, you need to track the following steps to partition it:

•    Select this drive in the left pane of Disk Utility and go to the Partition tab at the right
•    Click Options button below graphical view of the hard drive
•    In the opening window, select GUID Partition Table on your Intel-based Mac, and then click OK button
(Choosing GUID Partition Table makes this hard drive boot enabled for every Mac 10.4 and later)
•    In the Volume Scheme dropdown menu, select the number of partitions you want to have on your Mac
•    Now, select a partition and go to the Volume Information area
•    Type a Name, choose Format as Mac OS Extended (Journaled), and specify the Size for this drive
•    Now, repeat this step for other Mac partitions

Deleting Mac Partition
In any unfavorable situation, you may have to delete one or Mac partitions; following are the steps you can follow to delete Mac partitions:

•    Select this drive in the left pane of Disk Utility and go to the Partition tab at the right
•    Click to select the partition you need to delete in the graphical view of the hard drive
•    After that, click delete (-) button given beneath this view to delete it
(When you click delete (-) button, a warning message pops up that says all data stored on this volume will be deleted. Take required action to proceed.)

Creating a New Partition on Mac
After deleting a Mac partition, you see the free space in the graphical view of this hard drive. Go through the steps discussed below to create a new partition on Mac:

•    Click to select the free space in the graphical view of this hard drive, and then
•    Click the Add (+) button beneath this view to add a new volume
(By default this volume acquires all the free space. You can resize this volume if you want.)
•    Select this volume and give it a Name, choose its Format as Mac OS Extended (Journaled), and specify its size manually under Volume Information area
•    After that, click Apply button to save it

Modifying Mac Volume
Based on the amount of data stored on your Mac, one or more Mac volumes get full. In this situation, you need to enlarge these volumes. If required amount of free space is available on your Mac, you can use this space. Alternatively, your will have to shrink the other volumes. For the time being, let us modify one or more Mac volumes with Disk Utility:

•    Launch Disk Utility and select your Mac drive in its left pane
•    Go to the Partition tab in the right pane and select a partition containing free space in the graphical view
•    Hold this volume from its bottom-right corner and drag it
(Drag the volume upwards to shrink or downwards to enlarge. When you shrink this volume, you can see the free space increasing under the volume.)
•    Similarly, you can modify other Mac partitions
•    After that, drag the volume (that needs to be modified) downwards to enlarge it
•    Click Apply button to save the changes
As the alternative to Disk Utility, you can use a professional Mac partition manager as well. Make sure the one you use is reliable.

Repartitioning Your Mac Drive is Trouble-Free with a Reliable Partition Manager

Hard drive partitioning, though, is not a major concern; however, when it comes to partition the hard drive on Mac, it becomes quite complicated. In fact, many of the Mac users do not go for partitioning their drives. Well, if you have not partitioned your Mac drive, it must be having only one partition (i.e. the boot volume, Macintosh HD) containing system files. However, it is risky to save your data on the boot volume along with the system files. To know why it is not safe, go through the following:

Suppose, if your Mac fails to boot due to any unknown cause, then you would not be able to access your data. In this situation, you cannot even go for reinstalling Mac OS X since you need to format the boot volume first. If you format this volume, you lose your data permanently. In contrast, if you have partitioned your Mac drive into a number of partitions earlier and have all your data saved on them, then you can easily go for reinstalling Mac OS X. In fact, partitioning your Mac drive is all in your favor, as it not only keeps your data well organized, but also protects your data from each threat to the boot volume.

Mac OS X facilitates partitioning its hard drive into a number of volumes both during and after its installation. This actually means, no matter whether data is stored on your Mac drive or not, you can repartition it anytime based on your requirements.

Are you planning to repartition your Mac drive? Well, if yes, all you need to have is a professional Mac partitioning application, like Stellar partition manager that helps you perform all the partitioning related tasks (such as creating, managing, deleting, and erasing Mac volumes) easily as well as efficiently. In fact, this partitioning app is highly compatible with a range of Mac OS X versions (Mac OS X 10.3.9 or later). With this app, you can easily create, format, delete, hide/reveal, and resize Mac partitions even on Macs with least system configuration (i.e. Processor: Intel, PowerPC (G3 or later), Disk space: 25MB, and RAM: 512MB).

Key features
In order to figure out how this partition manager woks, you can download its demo version from the official website of the company. As for now, you can go through its key features:

1. This app is compatible with the latest version of Mac OS X (i.e. Mountain Lion)
2. Works efficiently on both GUID Partition Table and Apple Partition Map
3. Supports Mac volumes formatted as FAT
4. Facilitates creating new volumes using available free space
5. Able to resize Mac volumes keeping data intact
6. Features modifying existing Mac partitions
7. Features hiding/revealing Mac volumes for data safety purpose
8. Verifies data before modifying Mac volumes
9. Able to perform multiple tasks as batch operations
10. Optimizes the free space before modifying Mac volumes

Repartitioning Mac Drive
Partitioning your Mac facilitates you not only to store different types of data separately, but also to install multiple operating systems on separate partitions. By installing multiple operating systems on your Mac drive, you can access your Mac data even if one of the operating systems is crashed.

Apart from making data accessible and storage efficient every time, partitioning the hard drive keeps your data secure also. In fact, partitioning a hard drive on your Mac is not a major concern, though; however, repartitioning the same drive definitely is. Perhaps, you are confused. Well, partitioning a hard drive involves no risk, as it contains no data. However, repartitioning the same drive later on involves great risk of data loss. No matter how careful you are, you cannot repartition a hard drive efficiently without having a reliable professional Mac partition manager. Alternatively, in case you have a Mac partitioning tool like Stellar partition manager, you can easily repartition your Mac drive keeping all your data intact. Following are the steps your need to track for this:

Step1: Download and install Stellar partition manager on your Mac
Step2: After that, double-click it to launch
Step3: On the Software home screen, click the Continue button to go to the next screen
(Here, you see that home screen of the software is divided into three panes wherein, left pane displays all the drive installed on your Mac. In the middle pane, you see all the volumes of the drive that is highlighted at the left, whereas the right pane displays the complete information of the volume selected in the middle pane.)
Step4: In case, the free space is available on your Mac drive, highlight it and click the Add button in the toolbar.
(Free space is displayed beneath the last volume in the middle pane. After you click the Add button, the task to add a volume is added to the Task to do list, and then you need to click the Start button to execute it.)
Step5: If free space is not available on your Mac drive, then you need to shrink one or more volumes containing free space.
(The blue color displayed in a volume denotes data, whereas the white color denoted the free space in that particular volume.)
Step6: Hold a volume containing free space from it bottom-right corner and drag it upwards to shrink it.
(This adds the task to shrink a volume to the Task to do list. After that, you need to click the Start button to execute it.)
Step7: Likewise, you can shrink other volumes as well.
(The software throws a warning message every time you perform a critical operation. Click Continue button to allow the task to be done.)
Step8: Once the required amount of free space is available, repeat the Step4.
Step9: After you are done, exit the software.

Now, you see the required modifications are done. However, it is recommended to restart your Mac.

Partitioning Mac drive facilitates multi booting

Is it necessary to partition Mac drive? Well, even though it is quite apparent and easy question to come back with, many of you still ask for a precise explanation on why one should go for partitioning Mac drive.

Partitioning Mac drive not only facilitates storing different types of data separately, but also allows installing multiple operating systems on the Mac drive. The major advantage of installing multiple operating systems on separate volumes of a single hard drive is that you can access all your data even if one of the operating systems fails to boot.

How many partitions your Mac drive has? Only one! Alternatively, you can say that it is not partitioned yet. Well, you may not find your Mac drive partitioned into the number of volumes you want it should have.  However, you will have to partition it into the required number of partitions on your own. Luckily, Mac OS X facilitates partitioning its hard drive both during and after its installation (i.e. termed as repartitioning). At this point, you may wonder that why one would go for partitioning his Mac drive after installing Mac OS X on it. However, the reason would be none other than keeping his data protected from a number of threats to the Mac boot volume. Moreover, you must keep this in your mind that having thoughts about how to partition Mac drive will not be helping you keep your data protected, but putting this idea and your skills to partition Mac drive into action indeed would do.

When it comes to partition Mac drive, you should be aiming not only for saving all your data separately, but for keeping it protected against the threats (like Mac failure) as well. In case your Mac fails to boot due to some unknown reasons, the situation may not be in your favor, as you may lose all your data that is stored on the boot volume of your Mac. Therefore, it is recommended to partition your Mac drive into several volumes in order that you can keep all your data on the partitions separate from the boot volume. After creating multiple volumes on your Mac drive, you can multi boot your Mac as well. In case there is not any empty volume available on your Mac, resize other volumes and create a new one.

For this, you can easily resize existing Mac volumes on your Intel-based Mac using Disk Utility (or any other Mac partition Manager). However, though you can easily shrink all secondary volumes on your Mac drive, it is recommended to boot with Recovery HD (on your Mac Lion or Mountain Lion) or Mac OS X install disc (on your Mac OS X version earlier than Lion).

To boot with Recovery HD, you need to hold down the Command + R keys or the Option key when Mac is booting. In the Mac OS X utilities window, launch Disk Utility.
On the other hand, insert Mac OS X install disc and restart your Mac; press C key to boot with it. In the window that appears, select a preferred Mac OS X installation language and click the Next button. After that, launch Disk Utility in the Mac OS X utilities window.
You might be thinking that why you need to boot your Mac with Recovery HD or Mac boot disc, as you can resize Mac volumes when it is booted normally. Well, operating on the boot volume when booted from it may lead to its failure. At this stage, even a minor glitch or mishap may cause data loss. Therefore, booting with the Recovery HD or Mac boot disc is a wise decision, as both of these can be used as a bootable media.

Now, with Disk Utility launched, select your Mac drive at the left and simultaneously go to the Partition tab at the right. Here, in the graphical view of your Mac drive, the white color shown in every Mac volume denotes the free space, whereas blue color denotes data. This apparently means that you can shrink a volume within the range of white color appears on it. Based on the amount of free space you require to create a new volume, you can shrink multiple volumes as well.

For this, hold a volume from its bottom boundary (or bottom-right corner) and drag it upwards. Likewise, shrink other secondary volumes as well.

Shrinking a volumes using Disk Utility creates free space beneath it. The same issue is observed when you shrink another secondary volume. This means that free space is available, though; however, in the fractions. Therefore, you have to merge all these fractions in order to use the free space as a large block. For this, you have to enlarge and shrink secondary volumes in such a way that all of these fractions are merged and a large block of free space is available. Once it is done, you can use it to create a new volume. For this, track the steps discussed underneath: fuse

•    In the graphical view of your Mac drive, highlight the free space and click Add (+) button
(When you click Add (+) button, a new volume is created that by default acquires all the free space)
•    Once the new volume is created, do the following under Volume Information area:
◦    Highlight this volume and specify a Name
◦    Choose Mac OS Extended (Journaled) as its Format and
◦    Specify a Size (if required), and then
•    Click Apply button to save the changes that have been made so far

After that, you can install Mac OS X on this volume.
Though Disk Utility is able to perform all these tasks efficiently, it is not mandatory to use it for any operation like partitioning Mac drive. In addition, based on your own convenience, you can use a commercial Mac partitioning application as well. However, the steps to create a new Mac volume by resizing existing volumes may not be same as discussed above. Well, in case you are not comfortable with Disk Utility and need to switch to any other disk-partitioning tool, it is recommended to download a professional app to partition Mac drive easily and efficiently. For any help, go through the user manual provided with the app.

Stellar Partition Manager – A reliable tool to Partition Mac drive

“Do you think hard drive partitioning is complicated? Well, it might be; however, not when you have a professional tool, like Stellar Partition Manager. With this application, partitioning Mac drive is just like a few clicks of mouse. No matter which version of Mac OS X you run, this app can partition your Mac drive efficiently.”

Even though hard drive partition is not an issue of concern, it becomes complicated when the operating system platform that is going to use it is none other than the Mac OS X. Many of the Mac users do not even partition their hard drive and store their data directly to it along with the system files. System files? Well, if you have not partitioned your Mac drive, or more precisely, if your Mac drive has the only partition, it is the boot partition (i.e. Macintosh HD) that contains system files and it not safe to save your precious data along with the system to this drive.

Do you know why it is not safe? Well, in case your Mac is unable to boot due to an unknown problem, you would not be able to access your crucial files. In this situation, even reinstalling Mac OS X will cause data loss. Conversely, if your Mac drive has several partitions, any issue with Mac boot volume cannot affect your data at all, even if you reinstall Mac OS X to access your data.

No matter which versions of Mac OS X you are running, Stellar Partition Manager can easily resolve partitioning related issue.

How to resize Boot camp Partition on Mac

“Though everyone knows very well that Microsoft Windows is the most popular computer operating system, it is proved over and over again when Mac users around the globe go for it. Don’t believe? Well, you have to. Since Mac OS X offers support for installing Windows on its hard drive using its inbuilt application called Boot camp Assistant, this somewhere somehow also verifies the same.”

When it comes to install Windows on Mac, many of you do not believe it. Some even ask whether it is really possible to use both Mac and Windows on the same computer. Well, it is a fact that your Mac supports Windows installation; however, on a separate partition. For this, you can use a reliable Mac partitioning application and create a new partition for Windows. However, what if there is no free space on your Mac? You still do not need to worry, as you can trim free space from other Mac volumes and create a new one for Windows. For this, you need to follow the following procedure:

Go to Applications, open Utilities folder, and launch Disk Utility. Now, select your Mac drive in its left pane and simultaneously go to the Partition tab at the right. Here, as you can see the graphical structure of your Mac drive, the blue color in every volume denotes the used space, whereas white color denotes the free space. To trim the free space from these volumes, you need to shrink them all, but individually.

Important: To resize a Mac volume, your Mac drive should be using GUID Partition Table as the Partition Map Scheme, which in turn means that it must be an Intel-based Mac.

Remember that you do not try shrinking the boot volume (i.e. Macintosh HD) on your Mac, but the secondary volumes. For this, in the graphical structure of the hard drive, hold a volume from its border and drag it upwards within the range of the white color. Now, you see the free space beneath this volume.

Important: When you shrink a Mac volume using Disk Utility, the free space is displayed beneath that particular volume. Similarly, if you shrink another volume, the free space you trim from this volume will be displayed beneath it. Since free spaces are available in fractions, it is not possible to create a new volume using these fractions. If you use a Mac partitioning application to for such tasks, you do not face any such issue. However, you can resolve this by following the procedure discussed underneath:

For this, hold the next volume from its upper boundary and drag it upwards to enlarge it using this free space. After that, hold this volume from its bottom boundary and drag it upwards to shrink it. Now, the free space you see beneath this volume is the combination of the free spaces trimmed from both the volumes. Likewise, you can shrink other Mac volume as well. Finally, you will see that the free space available in each of these volumes is displayed as a whole beneath the last volume. Click this free space, and then click plus (+) button to create a new volume.

Now, give this volume a Name, Format, and Size (only if you want to set it manually). Since you need to use this volume to install Windows, make sure the Format you choose for it is MS-DOS (FAT), and then click Apply button to save it.

Resizing Windows partition during Windows installation

After that, Go to Applications, open Utilities folder, and launch Boot camp Assistant. On its home window, click Continue button to open the next window, where you see both Mac OS X and Windows partitions are separated by a thin boundary. Since Windows 7 requires at least 17GB free space to be installed, you can still enlarge Windows partition (if Mac OS X partition has free space available) by dragging the boundary towards the left. As you will install applications as well, keep the size of the Windows partition accordingly. Once you set the size of this partition, click Partition button to save it. Now, you can see this partition named as BOOTCAMP on the desktop.

In the next step, insert Windows 7 boot disc and click Start Installation button on the Boot camp Assistant Wizard. This restarts your Mac and then opens a window to select the partition; select BOOTCAMP partition. Now, click Drive options, and then click Format to do the same. In the pop-up message box, click OK button to allow formatting. After that, Windows installation will begin; eject the Windows 7 boot disc when your Mac restarts. On restarting, it automatically continues to boot Windows 7. Afterwards, you will be asked to select OS language, keyboard layout, and to enter the product key.

On completing Windows installation successfully, insert your Mac OS X boot disc and click Run setup.exe in the AutoPlay window. In the Boot camp wizard, click Next button, accept license agreement and then again click Next button. Click to enable the checkbox Apple Software Update for Windows and click install button. In the notification bar, a pup-up will notify you after every driver is installed. Once these drivers are installed, click Finish button to end up. Now, a message window will prompt asking you to reboot; click Yes button to allow.

To boot from Windows, you have to press the ALT key when Mac is booting; otherwise, it will boot to Mac OS X.

Resizing Windows partition after Windows installation
If you have an empty Mac volume and you want to merge this free space into the BOOTCAMP partition, then track the process mentioned below:
In the Run window, type “diskmgmt.msc” (without double quotes) and hit the Enter key. In the left pane of the Computer Management window, click Disk Management beneath the Storage tree menu, and then right-click the Windows partition to choose Extend Volume option in the context menu. In the Extend Volume wizard, select that volume to merge into it and proceed accordingly.

Mac Drive Partitioning to Avoid Data Loss due to OS X Crashes

Since Mac OS X allows its hard drive to be partitioned into a number of volumes, you can go for creating several volumes on it to make data storage efficient, unambiguous, and trouble-free. To partition Mac drive efficiently, all you need to have is a reliable Mac partition manager and experience in working with it.

Have you ever tried partitioning your Mac drive? Are you still using that un-partitioned drive since you do not know how to partition it? Hard drive partitioning, though, is not mandatory. However, partitioning makes data storage better as compared to when all data is stored along with the system files on a common partition (i.e. Macintosh HD), the Mac boot volume. If you think logically, then you can make out that apart from making data storage efficient, hard drive partitioning keeps your data secure against the threats of losing it. For example, if you save all data along with the system files on a common drive, you may lose it anytime due to Mac system crash. However, your data remains intact if you store it separate from the system files.

Additionally, by partitioning your Mac drive into several partitions, you not only can store different types of data separately, but can install multiple operating systems (i.e. Mac as well as Windows) on separate Mac partitions as well. By installing multiple operating systems, you can access your Mac data even if one of these (i.e. operating systems) is crashed. You can use a separate partition as a backup drive as well. Since partitioning tool is the key requirement for the process, you can also use Mac inbuilt Disk Utility as the default Mac partition manager. No matter whether you are going to partition an external or internal hard drive, steps to partition Mac drive are alike.

Important: To partition a brand new hard drive on Mac, first you need to initialize and format it. Conversely, back up all essential data before partitioning an already used drive.
As the very first step, connect the secondary hard drive to your Mac and verify that it is shown as a mounted disk on your desktop.

When you connect a brand new hard drive to your Mac, it pops up a Disk Insertion message that says “The disk you inserted was not readable by this computer.” Now, you need to click initialize button on the pop up message and it launches Disk Utility.
In Disk Utility, select secondary drive in the left pane and go to the Erase tab in the right pane of the window. Here, you need to click Format menu and select Mac OS Extended (Journaled). Type a Name for the hard drive, and then click Erase button to format it. When drive formatting is finished, click Partition tab with secondary drive selected at the left. Click Options button, choose GUID Partition Table (i.e. on Intel-based Mac), and then click OK button. Click Volume Scheme menu and choose the number of partitions to create on this drive. Now, one by one select each volume in the partitioned view of the hard drive, and set its properties (Name, Format, and the Size) at the right below the Volume Information area. If you want to install Windows on either of these partitions, click MS-DOS (FAT) as its format. Once finished, click Apply button, and then click Partition button in the pop up message.

Now, you can use these partitions to store Mac data separately and protected from the threats to system files.

An answer to why to Partition Mac Drive

Is hard drive partitioning necessary? Why should I go for hard drive partitioning?
Well, Mac users most frequently ask such type of questions. However, in order to make out why to partition Mac drive, one needs to read this post. Mac has a slew of system files that undergo repeated execution as long as it is running. If your Mac drive has only one partition (i.e. Mac boot volume), then you must be saving your personal as well as professional data along with the system files. In reality, storing your data along with the system files on a common drive is nothing but foolishness, as you may lose your data anytime due to OS X crash. Actually, you might be on the edge of data loss because you never know what happens in the upcoming moment.

Imagine a situation that your Mac drive has the only partition (i.e. Macintosh HD) containing system files in large number. Now, since several internal and external factors (such as forced shutdown, power fluctuations, and hard drive’s own structure) affect your Mac, even a minor glitch can cause failure of your Mac system, thereby ruining your all data. In such a situation, if you go for fresh Mac installation, all your data will be lost beyond recovery. However, to avoid all such risks of data loss, it is recommended to use partition manager Mac application and split your Mac drive into required number of volumes.

   Pros of Partitioning Mac Drive
How many partitions you have on your Mac? Have not partitioned yet? Here are the steps to partition Mac drive using Disk utility followed by some advantageous features of hard drive partitioning:

Your data remains untouched even if Mac OS X is crashed
A slew of factors affect Mac OS X when it is running as well as when it is shutdown. By storing all data separate from the system files, you can avoid the odds for data loss due to OS X crash that may surprise you anytime.

By partitioning Mac drive, you can store different types of data in separate volumes
As you are able to partition Mac drive into many volumes, you can store your different types of data (images, videos, songs, applications, and professional documents and reports) on separate volumes. This not only makes data storage efficient, but unambiguous as well.

By partitioning Mac drive, you can install multiple operating systems on it
Since a separate volume acts as a separate disk, you can install multiple operating systems (i.e. Mac as well as Windows) on separate volumes of your Mac drive. To install another copy of Mac, you need to boot from Mac OS X installation disc. However, to install Windows, you need Mac partition manager and Mac inbuilt boot camp assistant.

  Partitioning Mac Drive
Now, after you know why to partition Mac drive, track the following steps to partition Mac drive:
•    On Mac OS X Lion or Mountain Lion, go to Recovery Mode, or for Mac OS X versions earlier than Lion, boot with Mac boot disc.
•    Launch Disk utility in the Mac OS X utilities window.
•    Select your Mac drive in the left pane and go to the Partition tab at the right.
•    Click and hold the volume Macintosh HD from its border and drag upwards to shrink it.
Or
•    Click Volume Scheme dropdown list and choose number of partitions to create.
•    Now, click one partition and give it a Name, choose Mac OS Extended (Jouranled) as the Format, and specify its size manually. Repeat this step for other Mac volumes as well.
•    Finally, click Apply, and then click Partition button to save changes.
When partitions are created, exit Disk Utility and other opening windows, and then boot normally. Now, you can take the advantages of partitioning Mac drive.
