This is good, since the drive isn't totally dead then. It is running in some "Safe Mode" that will allow you to re-flash the firmware.
It shows the drive but does nothing (shows as empty) when a DVD is inserted.
A drive in Safe Mode will only allow you to flash proper firmware, nothing else.
Because it has OEM (gateway) lock on it.
It is 552D
With a "forced Flash" (see FAQ in my signature), this OEM lock can be overridden, which means, you could also flash retail or other OEM firmware onto the drive. IMO there is nothing to lose at this stage.
