Mac OS X hard drive is divided into various partitions, called volume, for effective management of your precious data stored on it. Every Mac computer has a boot volume, which contains critical system files that are required for your Mac OS X operating system-based computer to boot up. These files are pretty important for booting up your system. In case the boot partition gets damaged or deleted, your system become totally unbootable and unusable. It leads to severe data loss and require Mac drive recovery solutions to fix the problem, if there is no backup in place.
The boot volume of your Mac OS X operating system contains the following files:
Mac OS X operating system.
MBR (Master Boot Record).
BootX, Mac OS X boot loader.
Operating system kernel.
Binary files that are required for multiple kernel extensions.
Mach/BSD data structures.
Init, Mach bootstrap (service naming) daemon.
The boot volume of your Mac OS X hard drive must be a primary volume and set as active. This need can be completed on any hard drive on a computer that your system BIOS (Basic Input/Output System) searches when Mac OS X operating system starts.
There are some situations where boot volume of your Mac computer may get damaged and your system can not boot up. This behavior cause critical data loss and put you in need of disk recovery Mac solutions. Boot volume may corrupt due to any of the following reasons:
Improper system shutdown due to power outage, system crash, and user mistakes.
Accidental deletion of some critical boot files by the user.
Virus infection. Viruses are malicious programs that may enter your system through Internet, Email, or removable devices.
Operating system malfunction.
Missing or corrupt data structures, like file system, MBR, boot loader, and operating system kernel.
If you come across any of the above mentioned situations, you need to format your hard drive, reinstall Mac OS X operating system, and then restore data from backup. But, you may face critical situations if backup is not available.
In such situations, Mac disk recovery software come for your help to extract inaccessible data. The drive recovery Mac tools are particularly designed to scan entire drive and extract all inaccessible data from it.
