FWIW, my Panasonic CW-7502 CD-R drive gives a correct size in response to
a SCSI "READ CAPACITY" command. Are you saying that most drives don't
support this?

Anyway thanks for the tip about -isosize, that will definitely come in handy.
I've been trying to make more of a habit of copying CDs and working from the
copy, the same way anyone does with floppies, because for some strange reason
all my expensive commercial CDs always seem to wind up getting stepped on
eventually, and get scratched too badly to read. Especially the M$ ones...
