Colin's theory and suggestion seems pretty sound.
I remember reading back in the day of floppy drives, it was possible for
a drive to get mis-calabrated and successfully read/write data to the
disk, but all other drives would be unable to read it.
There's no reason why the same could not happen to a CD drive.
Perhaps your previous drive was slightly mis-calebrated, and the spacing
or angle of the pits were off. Some drives would be more accepting and
be able to read the disks but other drives may complain about it.
