Re: Solution from Scripting guys   

If you can take the time to post a link then
couldn't you also take a few more seconds to
explain what you're talking about?

  For the sake of anyone else who doesn't want
to chase down this link just to see if it might
be relevant to them, it's an article about
figuring out which disk a partition is on, using
WMI.
