Time Machine is an advanced and popular data backup tool in Mac OS X 10.5 Leopard and 10.6 Snow Leopard operating system. It is invented to work with Time Capsule as well as various external USB (Universal Serial Bus) and FireWire hard drives. The software enables you to restore entire backup, selected files, or even a single data file. This backup tool captures current state of data on your Mac OS X hard drive. However, you may face some critical problems with Time Machine volume after installing updates of Mac OS X 10.6 Snow Leopard. The drive gets locked and become totally inaccessible. This behavior cause severe data loss situations and require Mac recovery to be fixed.

After installing updates, Mac OS X 10.6 Snow Leopard makes entire Time Machine backup volumes inaccessible. The “Get Info” window is safe only for checking size of file, folder, or hard drive volume. You should not click the permissions tab at bottom of the “Get Info” window, or you may run the hazards of losing entire backup.

Sometimes the permissions can be changed successfully using Terminal application, however in some cases it may make your system unbootable, leading to serious data loss circumstances. In such cases, you may try this to work around the issue:

· Remove your hard drive, both Time Machine backup drive and data drive.

· Perform Archive and Install installation of Mac OS X 10.6 Snow Leopard operating system.

· If it does not work, perform Erase and Install installation of the operating system.

· Format Time Machine backup drive using another Mac machine.

· Backup data on Time Machine drive again.

When you go through the above steps, you may possible sort out your problem from system point of view, but you come across several new problems related to your data. Erase and Install installation of Mac OS X operating system removes all the data from hard drive and leads to critical data loss situations. At this point, need of Mac file recovery solutions arise.

They comprise of high-end scanning methods to thoroughly scan entire drive and extract all inaccessible data from it. Mac recovery software do not demand sound and prior technical skills as of their interactive graphical user interface.
