OPTORITE DD0203 (aka SANYO CRD-BPDV2)
Optotrite’s window firmware flashing utility is prone to failure. You will cause the firmware flashing utility to crash if you accidently press the “ok” button twice. If the firmware flashing utility crashed while it’s updating the firmware, then the optorite drive will appear to be dead (no LED light, no motor spinning noises) even during a reboot. Using the well publicized mtkflash recovery technique will not let you re-flash the optorite drive.
After spending an hour fiddling with boot menu and mode selction pins, i figured out how to make the optorite DD0203 work again. Here is how I did the recovery, 1) copied dvflash.exe and the firmware bin file onto a dos bootdisk 2) move the factory-use-only pin from the right most position to the 2nd right most position. 3) make sure the ide mode selection pin is not on cable select. 4)reboot your computer with the bootdisk 5)start the dvflash utility by typing "dvflash .bin". ( denotes the firmware filename)
6) follow the onscreen instruction (dvflash will automatically detect which channel your optorite drive is on) 7)move the factory-use-only pin back to the original position 8) reboot your computer once the recovery is completed.
I think the recovery can be done regardless of the IDE channel and master or slave position your optorite drive is occupying. The aforementioned instruction should also work for the MSI 4X DVD Writer and Sanyo DVD Writer since they all use the same chipset.
However, you may want to try re-flashing the msi or the sanyo drives without moving the factory-use-only pin before using my method.
