Pioneer BDR-S12U - UHD Issues: Is a Firmware Update Worth It?

#1 Post by bimbi » Sat Jul 25, 2026 6:35 pm

Hello all,

A few years ago, I bought a UHD drive here on the forum: the “PIONEER BDR-S12U.” It “mostly” worked pretty well. But over the last two years, it's gotten worse and worse. Lots of read errors, I/O errors, SCSI errors...
What helped was restarting the PC, cleaning the disc (even though there was no visible dirt), reinserting the disc, and trying again, and again, and again. Eventually, I’d get lucky and the copy would work. Sometimes I’d just exchange the disc on Amazon, and the replacement would work right away. It was all pretty strange.

Anyway, here’s the situation. Seven days ago, “Avatar 3”-> no problem. And now I’m trying to add the "Transformers 7 Movie Collection" to my media collection; so far, I’ve only managed to move two discs. And I’ve been at it for almost a week.

System: Kubuntu 26.04 LTS

Here are my drive’s specs:

Code: Select all

Drive Information
OS device name: /dev/sr1
Current profile: BD-ROM
Manufacturer: PIONEER
Product: BD-RW BDR-S12U
Revision: 1.01

Drive platform: RS8F01
Firmware name: PIONEER BDR-212T
Firmware type: Original (unpatched)
Firmware version: 1.01/ID43
DVD all regions: Yes
BD raw data read: Yes
BD raw metadata read: Yes
Unrestricted read speed: Yes

Disc Information
Label: REVENGE OF THE FALLEN

Data capacity: 89.15 Gb

Do you think updating the firmware would help?

I know it doesn't help right now, but it's incredibly annoying. You buy some UHD Movie you can't really use. What a shame that the movie market has become so complicated.

Best Regards :)

No, firmware has absolutely nothing to do with problems reading discs. Try cleaning the lasers.
Cheers :D

:lol:
no take it apart and clean it with lint free cloths and water or alcohol

eject tray
unplug drive with tray out
pop off front bezel clips on sides and bottom with plastic tool
undo screws from bottom will be under stickers if you have an s13, 213 does not have stickers.
flip backover and remove top cover
clean lasers with a lint free cloth or qtip and water or alcohol and dry with another do this 2 times and do not let it air dry you must remove the residue with a dry one!

Oh, okay, thanks a lot. I didn't know I could do it that way. I will do that over the next week :-)
