Very interesting.  How do I check the firmware version of the drive?
How do I install new firmware?  The Sony site is uninformative.

The construction list for the computer says Sony AD-7220S, however the
drive's front is blank.  Or maybe you mean the disk itself and not the
drive: the disk has a large label over it, so I can't tell what brand it
is.  The disk was burnt for me about 5 years ago.
