There is a difference between the Mac drive formatting and the drive wiping. Let us first understand why Mac drive formatting is needed. The reasons can be for the Clean System installation of Mac OS X on your new Mac drive. Another situation can be that the user wants to go for a larger drive, so that the movies that are downloaded need more space. But, the need for formatting starts with the use of a new drive.
It is easy to format a drive, but the decision to format a drive must be preceded with some planning for using the drive.
The formatting of the drive leads to erasing of all existing data. So, before the start of the process, the backup needs to be made. There are various ways to format an internal or external drive on Mac. These are using the Disk Utility, Mac OS X install DVD.
The application Disk Utility is opened, after attaching the drive, if one wants to format an external or extra internal hard drive.
Some users also need to partition the drive, with one visible partition in Windows and another one is the Mac OS X boot partition. The GUID partitioning scheme is required by the Boot Camp. In order to partition or resize Mac partition, we need to use the partition tab in Disk Utility or the Boot Camp Assistant can also be used.
If one is using the hard drive only for Mac OS X, then a specific drive format needs to be selected. The selection of the drive format, then Mac OS (Extended Journaled) can be used. The option is FAT 32, when the drive is also accessed from the Windows.
Mac OS X Install DVD
For formatting the hard drive inside the Mac, the same procedure will be followed but the booting has to be done from the OS X, using the Install DVD or from another Mac. While using the Install DVD, start the install process head to the menu bar and then the Disk Utility is selected. Mac OS (Extended Journaled) is the format, which is recommended.
Drive Wiping arises under such circumstances, when there is need for replacement of the drive or even the computer, which has become obsolete and is no longer serving the same purpose, for which it was bought. However, before this is done, one need to be sure about any information not being gained from the trash. This is where; the drive wipe Mac software comes handy.
You may want to give away your computer, dispose it by selling or donate it and adequate amount of precautions has to be taken, so that it is ensured that the personal and confidential information is passed to another user. We need to make sure that the precious data on the hard drive is not being recoverable. In order, the data not recoverable beyond any practical ability, we need a wiping or an erasing utility. This utility can even overwrite every sector with binary 0s and 1s. There are certain software, which meet the Government security standards and can overwrite each sector for multiple numbers of times for ensuring added protection.
Hard drive wiping is complete erasure of the drive of all information. Formatting / deleting do not wipe all information from the hard drive. There need to be extra steps taken for wiping the hard drive completely. While deleting a partition or formatting a drive, the file system is deleted, thereby making the data invisible but the data is not completely gone. A suitable hardware or a file recovery program can lead to the recovery of the information.
The Data needs to be wiped securely for protection from Data Recovery. The overwriting of the data can permanently erase the files.
There are certain circumstances, when we want all these private information to be gone forever. We must remember to have a backup of the data, because when the disk is wiped out, there is no chance of getting the data back.
There are various ways of erasing the hard drive completely, but a data sanitization software can be a good viable option. There are two procedures, while using the CD/DVD or using the flash drive or other USB drives.
In case of the CD/DVD, the ISO image to the disc is burnt and then booting is done from the disc to run the program.
While using the flash drive or the USB drive, the ISO image to the USB device need to be burnt and then booting is done from the USB drive for start-up.
The Data destruction program or the file shredder is the way data is overwritten on a hard drive or any other storage device and the means of doing it, is data sanitization.
There are professional software for permanently wiping unwanted and sensitive data from the Mac OS based hard drive. These software are equipped with powerful algorithms, which can ensure the permanent erasure of data, beyond the scope of any Data Recovery software. The important features are scheduling the wiping process or selecting of some of the files or folders, for the removal of the information. The software can also wipe temporary files like cookies, sessions and other internet files related to internet browsing information; it can also handle unwanted system traces, recent file histories. The software also allows removing the free spaces completely from where the data was deleted.
