This happens on a Windows SBS 2003 Server. Before I start there are no other known issues with this server...
Every night a few minutes into the SBS Backup this shows up in the system log:
Event ID: 55
The file system structure on the disk is corrupt and unusable. Please run the chkdsk utility on the volume System.
40 minutes later the exact same Event is logged. This only started happening a month ago. It now happens, without fail, every time the daily backup runs.
What I've tried:
Looked at a lot of KB articles that didn't seem to apply to this situation. One of them suggested running chkntfs at command prompt. I did that and was told that the drive is "not dirty." According to the KB article "no further action is required." That's all nice and good but I don't want to just ignore these errors and pretend like nothing is wrong.
Before anyone suggests running chkdsk /f or /x, this is a live server and if I am going to take it down and possibly break it, it is going to require some planning. What I think might be wrong is that there is 1 or 2 corrupt files that only get accessed when the backup runs. If that is the case I guess it could just be ignored.
Any suggestions or thoughts?
