I have just recently came acquired an optical SATA DVD-RW drive with "AD-7290H-H5", "Model No. [Oriental characters] AD-7290H", and "Manufactured Date: June / 2012" on its physical label.
The Nero InfoTool data for the drive (with serial number removed) may be seen in the attachment to this thread.
I have not been able to firmware for the optical drive.
I would guess that the non-OEM equivalent name for the drive would be AD-7290S.
I would like to make the drive RPC1, or if not possible/reasonably feasible, RPC2-Auto Reset.
Is the HP OEM AD-AD-720H drive a re-brand of another model? Is firmware to flash available for this drive?
EDIT: BinFlash GUI 1.62 seems to have dumped the drive's firmware successfully. The dump file's file size is 1,769,480 bytes.
