Odd behavior on XP

[Geoff Canyon]

I'm searching for the inserted cd's drive letter on an XP machine by 
looking for a file on the cd using each of the drive letters in the 
volumes. On other PCs this works fine; on the XP machine it brings up 
an insert media warning/dialog for each removable drive that doesn't 
have something in it. Is there another way around this? Are others 
using XP seeing this?

regards,
