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

Dell Optiplex 3010
WD5000AAKX

Windows 7 Pro SP1 64 bit

This is the drive containing the OS and was just replaced on July 23. I restored the disk from backups using Acronis True Image 2014.

Starting on July 25, I started seeing

The file system structure on the disk is corrupt and unusable. Please run the chkdsk utility on the volume OS.

in the System event log (Source Ntfs, Event ID 55).

I ran a CHKDSK /R on the drive and it reported no problems with the drive.


Other than the scary messages in the System event log, I'm not seeing any problems, but I'm also not seeing these errors on the other drive in the machine.

[I neglected to mention that the drive passes the pre-boot diagnostics]

What's going on here?

I didn't see anything in the PC Magazine article that directly addressed the problem. Were you talking about the overall complexity and opportunities to seriously screw things up with True Image?

Also, the link to the Microsoft solution gets me to "We are sorry, the page you requested cannot be found"

However, I think I've found the fix, and it's entirely software related.

After scouring the system and application event logs, I realized that the error I've been seeing was always bracketed by the VSS subsystem starting and stopping, and was almost always related to either a virus scan or a backup operation.

Some research (googling, actually) let me to suspect that the retained shadows of the drive were somehow corrupt, so I simply deleted them (vssadmin delete shadows /for=c: /all). Since then, there have been no errors reported, new shadow snapshots were created and everything else is working OK.

Hi rbobby,

I would run a couple diagnostic utilities, including the Dell diagnostics and maybe the drive manufacturer's diagnostic.

You could try running WD Lifeguard Diagnostic utility for your drive. Try running both the short and long scans and find out if it will able to correct the problem.
