Spoofing (changing the dvd drive MFR and making it report as the original drive) is
easily detectable using vendor specific commands.

Use that to identify your drive (or look at it as you've already opened it)
If you want to protect Live, get the same MFR of drive, open the drive and swap the pcb's ...
At worse you'll have to solder 6 wires if its a LiteOn.
This will mean the FW never changes and you cant be banned.
Alternatively, buy a laser for your drive (if you tell me MFR, Ill tell you model numbers)
If you need a spare drive, I've a mate that stocks them.
