The file system structure on the disk is corrupt and unusable ...

Thread needs solution

Windows 7 Pro SP1 64-bit
Acronis TI 2014 build 6673

Could a full partition recovery (or disk clone operation) be causing corruption of shadow copy snapshots? Is recovering the shadow copies a bad idea in the first place?

After replacing a failed system disk drive and using TI 2014 to restore my last backup, everything seemed fine externally, but I started seeing that scary message in the Windows System event log over and over.

Everything seemed to be working correctly. A boot-time CHKDSK /R found no problems.

Since I'd just replaced the drive, I still suspected hardware problems, but all hardware tests passed, and other than the messages in the log, there were no symptoms.

Scouring the application and system event logs, I discovered that each error was bracketed by a VSS start and stop, from either a virus scan or a backup operation.

I used VSSADMIN to delete the shadows on the drive

VSSADMIN DELETE SHADOWS /FOR=C: /ALL

after which I've seen no more errors and the shadow snapshots have been re-created.

I have an older machine which does nothing but run my ham radio equipment on which I'd cloned a 250GB drive onto a 500GB drive with TI 2014 a long time ago. Looking at the event log for it for the first time in a very long time, I found exactly the same pattern of errors. I applied the same fix with the same (apparently) positive result.

If you do a full restore, then you have interrupt the vs process. I thought ATI took care of this but I can't recall last time I looked at the Event Log. Is there more than one partition and do yo see the prob is you do a full disk restore? The vs might be in another partition and when you restore one partition and not the other, you interrupt the vs process.

It was a "full restore" in the sense that I was moving to a new disk, fresh out of the anti-static bag. I booted from the Acronis recovery media and did everything from there.

I had done a "disk backup" of all 3 partitions of the disk, the OEM partition, the recovery partition and the OS.
