You can't.  You can make educated guesses.  If the drive # is 1 or 2 it 
GENERALLY is a floppy drive, but a 4 or 9 could be too (especially if its a 
Daynaor Rapport external floppy drive).  You can check what driver is running
the drive ('.Sony' would tell you that the Sony floppy driver is running, 
though Rapport also uses this name to fool other callers into thinking its a 
Sony driver).

You again could see if the AppleShare driver owns the drive.  There's probably
other ways too...

I don't know.  I know you CAN eject AppleShare volumes; it justs removes their
access from you (off the desktop).
