What risks are involved with flashing a hacked/patched/modified NEC firmware?
Any unofficial firmware that is not provided by the manufacturer will void your warranty! If you do not know what you are doing, do not flash your drive! Firmware patchers refuse to be responsible for the misuse of a patched firmware. USE THEM AT YOUR OWN RISK. It is also possible that a misflash can occur, such as a power outage occurring in the middle of a flash or some other occurrence. In this case your drive might not be functional at all! It is possible to recover the drive after this by reflashing in DOS, but it is not guaranteed to work.
