Does anyone know how to get a drive number from a volume reference number?
I use SFGetFile to let a user open a file.  AFter that i need to see if the 
volume the file is on is ejectable or not.  The only way i know of doing
so is to look thru the drive queue, but i need a drive number for that. (There
is a bit i can look at with assembly to see if the volume is ejectable)

Thanx,
Michael O'Rourke
