Trouble identifying which disk is throwing errors

I am getting an error that \Device\Harddisk3\ is throwing bad blocks.

I am having a hard time determining which disk this is. It says disk 3, but I do not seem to have a disk 3...

See screenshot.

Diskpart hit enter
select disk 3
detail disk

Edit: Just realizing from your attachment you ran diskpart and did not see a disk.

Do you have any external media attached USB etc ?

Do you have a RAID configuration, its a long shot but maybe IRST(or similar) is saying disk 3 on a raid array is going bad?

Download Hard Disk Sentinel from http://www.hdsentinel.com/

It is free to try and will give you health status of each disk, Brand, Model and serial number.

It will help you determine which disk is playing up and what the problem is.

Actually you do not have there so many disks so identifying must be really easy. Run on each disk partition CHKDSK x: and see what the report say. If you have bad block it will let you this know.
But Disk3 in your case is the Disk2.

This turned out to be an external USB disk. I unplugged it and the errors went away, replugged it and they started occurring again. Our monitoring software has detected this same error for multiple clients, always an external USB device. As such, I think this is safe to ignore, as these devices are only used for backup purposes anyway.

Thanks.
