I have Windows Server 2008 R2 with Hyper-V and one VM with a Pass-Through disk. Naturally I can't take a snapshot (it's a limitation of Hyper-V) but can I use a scrip to the unmount disk, take a snapshot and then remount the disk?

What is the underlying storage system for that disk? Is is it a SAN that supports snampshots? – Zoredache Mar 18 '10 at 16:35

Yes, you can. See Ben Armstrong's blog for information about constructing your scripts.

My bigger question to you is why you think you need a pass-through disk?
