I am looking for a batch command to retrieve an USB key manufacturer serial number. I need a command that works in both Windows XP and Windows Seven.

This is for a hardware follow-up. I have a script that sends emails when a problem occurs and it needs to include a way to identify the removable disk.

At first I used vol e: but the number changes when the disk is formatted.

On several sites I saw wmic diskdrive get serialnumber but it doesn't seem to work (at least on W7). The command returns Invalid XML.

This is not surprising. I ran wmic diskdrive get /? and the available options are:

No SerialNumber...

Do you have a better idea?

What do you mean by "doesn't seem to work"? – gronostaj May 27 '13 at 12:23
I edited my question. – Maxbester May 27 '13 at 12:28
wmic diskdrive get serialnumber does seem to return multiple 40-digit numbers (one per drive) on Win7 x64. – Karan May 27 '13 at 23:35
Gosh... Why doesn't it work for me?!? What is the cause of the Invalid XML error? – Maxbester May 29 '13 at 7:55

I've finally found the solution on Stackoverflow.

The SerialNumber property doesn't exist.

I now use:

wmic diskdrive get PNPDeviceID

But a fix exists from Microsoft here.
