Only HDD's have keys matched to the EEPROM, though you can lock a new HDD with a matching key.
Duh..... I had HDD on my mind.
The DVD drives are totally interchangeable, but do have those funky connectors though.
So yeah, another dead box, or ordering one.
A standard drive can be made to work, but not such a pretty install.
Or possibly tear into the drive and clean the laser assembly, that cures a lot of non-reading drives. (unless it's just dead dead)
