Problem

When creating a disk image you may see one or both of the following errors in the Image log:

Backup aborted! - Unable to read from disk - Error Code 2 - The system cannot find the file specified

Or...

Error reading MFT - Error code = 2. Please run 'chkdsk C: /r'

This can often be caused by the Volume Shadow Copy, used by the imaging process, force deleted mid backup by the VSS sub-system. Typically this is due to insufficient space allocated in the shadow copy storage area. You may also see an event similar to the following in the Windows event log:

Volume Shadow Copy Service error: Unexpected error calling routine Cannot find anymore diff area 
candidates for volume \\?\Volume{5f0981E1-b839-50f1-8456-0be0d0369d67}\ [0]. 
hr = 0x8000ffff, Catastrophic failure

Solution

To resolve this error run the following command from an elevated command prompt:

vssadmin Resize ShadowStorage /For=c: /On=c: /Maxsize=10%

Change C: for the correct drive if necessary.
