Creative 121032 based on Plextor?



Looking at G@M3FR3@K 's Ultra handy Safedisk 2 page
( ) it appears that the creative drive is based on a plextor.

whats this mean exactly ? what is different ? what is the same ?
can i use the firmware for the plextor on the creative and get myself a plextor ?

will the drive be detected as a plextor ?

any other info would be much appreciated.
does anyone own one of these drives ?
are they anygood ?
