Error message when you run the ChkDsk.exe utility in read-only mode on a computer that is running Windows Vista or Windows Server 2008: “The Volume Bitmap is incorrect”
Consider the following scenario:
- You create a volume on a computer that is running Windows Vista or Windows Server 2008. The size of the volume is a multiple of 8 gigabytes (GB). For example, the size of the volume is 8,192 megabyte (MB), 16,384 MB, or 32,768 MB.
Note: 1 GB equals 1,024 MB.
- You extend the size of the volume by using the Disk Management tool or by using the Diskpart.exe utility.
- You run the ChkDsk.exe utility on the volume in read-only mode.
Note: If you do not specify a switch when you run the ChkDsk.exe utility, the ChkDsk.exe utility runs in read-only mode
In this scenario, you receive the following error message:
The Volume Bitmap is incorrect.
Windows found problems with the file system.
Additionally, if you restore data that was backed up on the system, the restore operation may not finish successfully.
