semaphore timeout

P: n/a
Hi, has anyone gotten the error "semaphore timeout" when trying to do
a backup to disk? The disk is a logical partition. There are two
drives, c: and d:. Backing up to c: is fine. However, backing up to
d: produces the error below. Thanks in advance for any help.

Here is the command : backup database model to TestM2

This most likely means your hard drive is about to fail or has corruption.

I've done more troubleshooting and have determined that "backup log"
works, whereas "backup database" does not. How weird!

Also, I ran chkdsk, but it does not show anything. It's an NTFS, so I
think it might be better to run upon reboot. But here are the
results.

Thanks again for any suggestions/help!

The type of the file system is NTFS.

Anytime I've seen this error it was due to a problem with hardware in the disk subsystem. Maybe a
SCSI cable is bad, or your RAID card is getting flaky. These things might not show up in a
CHKDSK; you might need to use some of the utilities that come with your RAID card to evaluate the
disks' health.

D Newton,
Thanks for your help. It did turn out to be a bad disk problem. When
we ran chkdsk /r, it discovered some bad sectors. We ran chkdsk to
fix them. After that, we de-fragged the disk. The backup worked fine
after that.
Thanks, Margie
