_DRIVES?

[vefatica]

I'm not aware of M: and N: (not as SUBST's either). Any idea where they are coming from?

v:\> echo %_drives
C: E: F: G: H: I: J: K: L: M: N: P: S: T: U: V: W:

Try this BTM and see what it reports:

@echo off
setlocal
setarray types[9]
set types[0]=Unknown
set types[1]=Invalid
set types[2]=Removable disk
set types[3]=Fixed disk
set types[4]=Remote (network) drive
set types[5]=CD-ROM
set types[6]=RAM disk
set types[7]=DVD
set types[8]=Tape

for %d in (%_drives) echo %d - %types[%@drivetypeex[%d]]

unsetarray types

Never mind. They're my DVD drives. I haven't used them in years and forgot they were there. They don't show in the left pane (tree view) of MyComputer and I rarely see the right pane.

Ah yes, Windows hides empty drives by default. File Options->View tab->Hide empty drives in the Computer folder.
