Data Loss due to Programs that manipulate Volume blocks in Windows Vista and Windows Server 2003

Certain programs like Disk Defragmenter that are executed during the booting process (either directly or by using the FSCTL_MOVE_FILE control code) of Windows vista can cause data loss or data corruption. In such situations, the user is unable to start Windows and the drive volume also becomes unmountable. If there is no backup available, to access the data saved in the drive volume a user needs to use efficient Data Recovery Software.

Both Windows Vista and Windows Server 2003 operating systems use files saved in the "VolumeName\System Volume Information" folder to store information that is related to snapshots that are created by the Volume Shadow Copy Service. The Globally Unique Identifier (GUID) that is assigned to all the file names is {3808876B-C176-4e48-B7AE-04046E6CC752}.

Data loss or corruption mainly occurs when a program (Disk Defragmenter) changes the location of the blocks that are used by files early in the boot process. Another possible reason for data loss can be the overwriting of the blocks that are used by these files. To resolve the above problem and access the data in the inaccessible drive volume, the user needs to format the hard drive and reinstall Windows (Vista or Server 2003) operating system. To reuse his valuable data files, an affected user needs to restore the lost data from latest back up. But if the user has not maintained any recent back up, then he needs to recover the data by using a third party application known as Data Recovery Software.
