How to identify which device corresponds to \device\harddisk2

networkn used Ask the Experts™
I have errors periodically appearing in System log that read like this:
"An error was detected on device \Device\Harddisk2\DR82 during a paging operation." (the numbers after DR change each time)
I also get random pop-ups saying that "the device in drive G: needs to be formatted".
The problem is, there is no harddisk2 or drive G:. Disk Management only shows disk 0 (containing C: and E:) and disk 1 (containing F:) and also a cd-rom D:

How can I find out which device tries to pose as disk 2? Any logs or queries to do so?

Hardware is HP ProLiant ML350 G6 running Windows Server 2008 R2.

Run elevated CMD window

Then run program DISKPART

Write command

list disk and click enter
Compare all disk by capacity
You going to be able see disk 2 capacity and probably you going to be able verify what disk you have problem with.


As expected, there is no Disk 2 in the output.

So it maybe computer loosing connection to this device periodically ?
Maybe this is some USB device like flash Drive or micro memory card or some card in printer.
Look around !

Can you post screenshot from your diskpart window ?

Windows event viewer is 1 based,  diskpart is 0 based so if event viewer says hardisk2 dispart list disk it will be disk 1
A screen shot of diskmanagement would be helpful and diskpart
David, you're wrong. \Device\HarddiskX starts with 0 as well so numbers correspond to diskpart/diskmanager.

I've tracked these extra device appearances to coincide with ShadowProtect backup runs. The mystery is not completely solved, but it seems to be something to do with VSS layer.
