false disk corruption errors in system logs?

I have a Dell T420 that is running SBS 2011. Starting a few days ago, we started receiving disk corruption at random times, error listed below:

"The file system structure on the disk is corrupt and unusable. Please run the chkdsk utility on the volume \Device\HarddiskVolume2."

On this server, we are also running dell server manager which would show predictive failures of the disk drives. Server manager shows that the disks are fine (no predictive failures)

I am not entirely convinced that there is a failing hard drive in this server due to this conflicting information.
Does anyone have any ideas?
I'm stumped

The "drive" might be a USB key. Not doing the "safely remove hardware" thing can cause corruption on them, and these errors.

File-System corruptions and failing disks aren't the same thing and they don't necessarily need to be connected. Chkdsk doesn't look at the hardware, but rather only at the file-system. So you can easily have file-system corruptions on disks that are healthy.

I think I would trust server manager, which is looking at the hardware.  Is this a RAID array?   Has anything been changed or replaced lately?  

Dell's first response will be to tell you to get all the firmware up to date (BIOS, SCSI controller, and drives) and then Open Manage.

I'd start with Open Manage first as it's the simplest .  Update it to the latest and then check the alert logs and see what's going on.

Chances are though you do have a drive on the way out.

i would just run chkdsk  -and see what the result is - that should clear it up

Hello everyone - running chckdsk did not fix the issue, in fact it would try to run the chkdsk and fail very quickly.
We booted up with a O/S CD and ran it outside the O/S.  This seems to have resolved the problem.

Thanks!
