Finding USB volumes on Win

[Richard Gaskin]

In January with the help of Phil, Peter, and others I got some great 
tips for identifying removable drives on OS X and Linux.  But I'm having 
difficulty figuring out how to do the same in Windows.

I can find the registry entries to determine which devices are mounted, 
but they don't contain the info which will let me know which drive 
letter they're associated with.

I've tried setting the shellCommand to "diskpart" and then using:

get shell("list volume")

...but that returns "2", which means a syntax error, even though that 
syntax works fine from the command line.

Any tips on how to identify mounted removable volumes and obtain their 
drive letters?  Extra bonus points if I could get their names too, for 
those that have been named.

TIA -
