anipulating the volume blocks in Windows Vista and Windows 2003 server may cause volume corruption and file loss. The volumes in this case may become unmountable and the data stored on them may not be accessed. To sort out such issues, you are strongly recommended to go for file recovery software.
The programs which manipulate the volume blocks while booting the system, either directly or with the help of FSCTL_MOVE_FILE control code, might result into data loss or partition corruption in Microsoft Windows Server 2003 and Microsoft Windows Vista. In this case, hard drive volumes might become un-mountable. Furthermore, you might not be able to boot Windows.
1. Defragementation applications which work early in boot process, before Autochk.exe program completes, are an example of the type of program that might cause this problem.
2. FSCTL_MOVE_FILE control code moves one or more virtual clusters of the file from one cluster to another in the same volume. It is used while defragmenting the hard drive.
This behavior of Windows makes your system unbootable and file loss occurs.
Cause
The Microsoft Windows Server 2003 and Microsoft Windows Vista use file in 'volume nameSystem Volume Information' folder for storing information which is related to the snapshots which are created by Volume Shadow Copy service. These system files contain name that have following GUID (Globally Unique Identifier):
{3808876B-C176-4e48-B7AE-04046E6CC752}
When any utility changes the location of the blocks which are used by these system files early in boot process, you may face this problem. This issue may also take place when a tool overwrites the blocks which are used by these files.
Resolution
To overcome this problem, you can take the following two steps:
a. Format your hard drive and reinstall the operating system that would solve the problem but cause further data loss.
b. Carry out file recovery to scan your hard drive and recover corrupt partitions and files from them.
The recovery is best possible using third party File Recovery Software. These software are powerful enough to thoroughly scan your hard drive, locate the lost data and then recover it. These software are user-friendly tools to safely recover the lost data and achieve efficient File Recovery.
