I thought optical drives had *huge* amounts of ECC that was inherent in
the way the CD format was specified. And a drive that doesn't do ECC
won't be able to read the disks.

http://www.disctronics.co.uk/technology/cd-rom/cdrom_spec.htm tallies
with my memory.

So it should always be on, regardless of OS.
