I have a BenQ DW1640 drive that has BSOB firmware.
I accidently did something that I'm sure others must have also done once before, but it seems to have had dire consequences. I accidently put two discs into the drive at once (i.e. one on top of the other). I realised fairly quickly that something wasn't right as it made a very strange sound during spin-up. Within a few seconds I quickly ejected the drive.
But that's when the problems started. At first the only problem was that it stopped recognising the presence of DVD+RW discs. But now it won't write to anything. The burn process stops very early. It doesn't seem to read anything either. It seems to just hang Windows Explorer when I put a disc with data into the drive (doesn't hang when inserting blank discs)
I tried upgrading the firmware. I tried with the official flasher and with BQFlasher. Both produce error messages - "Updating incomplete or interrupted", and "Flash command failed".
BenQ Qsuite 2.1 seems to detect the drive and show it's properties, etc. fine. It even returns the manufacturer info on blank discs.
I'm expecting that this drive won't be able to be revived, but if anyone has any ideas it'd be much appreciated
