hi, thought I'd responded to this earlier but seems I didn't.
I'm using HP discs, burning at about 1/2 the max speed of my burner,
trying (not always succeeding) to keep cpu and disk usage down during
burning.  I *still* get the occasional coaster, which sucks when I'm in
the middle of an install and suddenly everything stops working.  I would
like to be able to check the integrity of the burned cd's after I burn
them.  Is there a way to do this with md5sum?  Anyone know?
