Shuffled the optical drives on my desktops. My Win7 machine had a pair of LG BluRay burners - WH12LS39 and BH12LS38 - from 2012-2013. For a few years now both have been in a peculiar failed state - reading/writing CD/BD fine, but only recognizing 1/5 or less DVD discs - burnt or pressed - doesn't matter. My Win10 desktop has a WH14NS40, which works fine, but has developed an "angry tray" syndrome - the tray closes immediately upon opening, unless held with force. It's annoying.
So I ordered one of these BH12LS35 from China. No idea if it's a fake, or some legacy production line, but according to the label it was manufactured in 2021, and together with some old LiteOn picked up from recycling, I seem to have three functional drives again. At least they read all types of discs, haven't tried burning yet. I've put the LiteOn in the Win10 desktop and both LGs in the Win7 system.
The LG WH14NS40 tray now sometimes stays open. Usually after 2nd or 3rd attempt. Not sure if it's a worn belt, a dirty/faulty sensor or what not. I may try to grease it or mess with it somehow if it gets too annoying. With all the semi-dead optical drives I have enough spare mechanical parts, but transplanting them isn't always easy. Last time I needed a working optical for my parents' computer I ended up getting a good belt from a drive with a dead laser and putting it in a good drive with a stuck tray.
The WH14NS40 is the only drive in my possession that supposedly reads and writes BD-XL (100GB) discs. Supposedly, because the only two discs I've ever burnt end up with CRC errors trying to read them back on the same drive. These were Verbatim discs ordered from Japan, so not rock-bottom garbage. I don't have another drive to try them on. Reading online it seems that any modern BD burner you buy tends to malfunction within a relatively short period of time. The age of optical media for backup/archival purposes might be drawing to a close, even for retro-enthusiasts.
