[qanda]This thread is about the Lite-On SHM-165H6S. Click here to see full specs[/qanda]Both my SHM-165H6S HS0E (stock) and SOHW-1633S BS0Y (stock) have problems reading DVD movies that don't appear to have any defects or scratches.
Last night I pulled both out of the case and took them apart. I blew out each of them with canned air and wiped the laser lenses with a microfibre cloth. Didn't see any obvious discoloration on the pc boards. After re-assembly and re-installation, I fired up the PC and tested again. My cleaning didn't appear to make much difference as both still had problems reading DVD's.
Both drives show a transfer mode in use of UDMA-2 on 40 Conductor cables.
I'm guessing the lasers are getting weak. Is there any point in re-flashing the firmware? If so, should I try cross-flashing them both to a modded FW?
I went ahead and ordered a Lite-On iHAP422-08 and a Pioneer DVR-1910 (either DVR-116DBK or DVR-115DBK, won't know for sure until it gets here) from Newegg. I should receive them sometime this week.
