I have two CD/DVD drives designated K and M but an additional drive, designated D: (the phantom drive) also shows in Windows explorer. This drive does not appear elsewhere or at least I can't see it in the Registry, Device Manager or Computer Management and it does not show during 'Post'. I have no idea when this phantom drive first appeared But I think I would have noticed it if it was there when I first installed Win7 (now 4 or 5 months ago). While this 'phantom drive' is harmless as far as I can tell I would like to get rid of it but as I cannot find it, other than in Win Explorer and in Directory Opus (my preferred File Manager). Does anyone have a suggestion on how to deal with this?
