windows 7: Event 55 The file system structure on the disk is corrupt and unusable

My Windows 7 (64) keeps completely locking up, and I have to hold the power button to shit it down. Event logs are showing EventID 55. I realize that this can be a warning sign of an impending disk failure, but my data on this machine is safely backed up and I don't feel like taking the time to replace the drive right now.

When I have seen this problem before, I have been able to delete the offending folder with a Linux Live CD. (When CHKDSK /F didn't work). In this case, the folder is from VSS. I assume this is from Crashplan, my online backup provider. What are the ramifications of deleting this folder from Linux? Is it safe to do?

"The file system structure on the disk is corrupt and unusable. Please run the chkdsk utility on the volume \Device\HarddiskVolumeShadowCopy26."

It's time to perform a disk diagnostic like Hitachi Drive Fitness Test (free) to diagnose if the disk is in fact, failing. Otherwise you'll be on a wild goose chase.

I did try running Western Digital's Data Lifeguard tool. It detects bad sectors, and when I try to repair, I get the fantastic error message "Error detected while repairing bad sectors." –  SomeGuy Nov 20 '11 at 18:36
    
Bad sectors aren't something that can be "repaired"; they usually just get marked as unusable and it's up to the firmware to relocate them. –  grawity Nov 21 '11 at 12:55
