The X-ray machines shouldn't be affecting CD-Rs. The
magnetic fields around the X-ray emitter are strong enough to
potentially affect magnetic disk drives -- but the emitter is
typically far enough away from the drive belt for the field to fall
off and not be a threat (my laptop has been through many X-rays --
including european ones that tend to run higher intensity).

Have you ever, before, tested the CD-Rs you've burned on
another computer? (Okay, I'm assuming, first, that they are one-time
CD-R and not CD-RW). Did you use a "drag&drop" style burner,
multisession burn, or a dedicated disk burner where you layout the
file order first. Did you CLOSE the disk at the end of the burn.

The most compatible is one-time CD-R, using a dedicated
burner in single session, with close.

Drag&Drop multisession CD-RW, with the disk left open is the
least compatible -- you run the risk that only the machine that
created the disk can read it later.
