  Check the kernel log (it's on one of the Virtual Consoles,
[CTRL]+[ALT]+[F4] maybe?) for indications as to what the kernel thinks
is going on.

  While it could be software (something with how the kernel is
interacting with the ATA controller and CD drive on that computer), it
could also be that the disc is marginal, so that particular drive
can't quite read it, but others are able to.  ("Newer" drives aren't
always better.  Sometimes engineering advances are used to reduce
overcapacity right down to the edge -- which lowers costs but makes
things less robust.)

  Along that line on inquiry:

  Burn another CD, preferrably with a different burner drive and with
a different brand of media.  Try the mediacheck of that disc on the
problem hardware.

  Try removing the drive from the problem computer and putting it in
one of the other computers that worked.  See if the mediacheck passes
then.

  Try taking a drive that works and putting it in the computer that's
giving you trouble.  See if the mediacheck passes then.
