Well lets say that this is a write once chip.
It might be very expensive and a pain in the fucking ass but I still think it would be possible to hack.
I don't know anything, but I am presuming that if this is indeed a once write chip, it is like a CD-R, current drives are like CD-RWs.
If you can read the firmware somehow, then buy a blank CD-R (a blank Firmware chip) and then flash it with hacked info.
Of course, soldering, desoldering, buying a new chip...sounds like a bitch, but if worse comes to worse, I would say that these drives might be able to be hacked....
