You can rip both and see if maybe one has chapters and the other doesn't. Another thing to check is the Source file name and/or Segment map in the Title information section on the right side (after selecting a Title on the left side). Sometimes that's a dead giveaway of which one is 'more correct' (...

Did you realize that you can have MakeMKV ask you which drive to attach to on start-up? Start the program, use the wrench icon to enter setup, click on "IO", select "single drive mode". Save the configuration. Restart MakeMKV. You will be asked whether to operate in all-drive or...

Yes, it is common that there are many different pressings that have different discID and a different 4 characters at the end of the dump file.

I suppose since they hash/checksum differently, the KeyDB needs submissions of each so that it can be kept up to date with all the various pressings?

The help text of https://www.makemkv.com/errors/read/ is mostly correct, but can be misleading. https://media.licdn.com/dms/image/D5622AQGHAKH0aNW7jw/feedshare-shrink_2048_1536/0/1696435627211?e=2147483647&v=beta&t=XxGLys0d8yF0cfj3ZBd4vs8TqE7WNs3XN5aJ91tXe0Y Below, I've quoted the relevant t...

There must be a LOT of bad discs out there and I keep losing the lottery. I've tried 3 distinct copies, each new & sealed, each tried raw (only removing little bits of dust or case plasticizer smudge), and the latest ones tried by cleaning with isopropyl and then warm soapy water, dried thorough...

I have a non-steelbook version and it wouldn't read on 1.18.2 with a moderately recent cfg. I tried, and it generated a 1C8C.tgz file. I then ran a KeyDB helper Synchronize (which worked) and a Validate (which failed), and then tried again. This time, a 1C8D.tgz file was generated.

Curious.

Thank you so much! I searched in vain for that post...

Clean it anyway... Sadly, no dice. I cleaned it again, thought I might have got some manufacturing glaze off, but when I tried to re-process it... it failed again. Same error cropped up within seconds of trying to back it up. It's worth noting there wasn't any abnormal power demand placed by this d...

Clean it anyway. Sometimes, well with UHD discs anyway, when brand new they can have an invisible to the naked eye film/mark on them. It certainly won't hurt for you to give it a good wipe with a microfiber cloth. Yeah, I've definitely found that as well. Same problem with older discs as the plasti...

The drive is having trouble reading a section of the disc and seems to be running out of power. Ensure you are providing adequate power, either via USB-C, USB-A ports direct from the motherboard or a self powered USB hub (30w+). Cleaning the disc will probably also help! Interesting thought on the ...

So, the recent Arrow release of The Cell (2000) has 2 discs. The first one (UHD) backs up fine. The second one is Blu-ray. It plays fine in a UHD or Blu-ray player, but it spits out these errors in MakeMKV 1.18.1 using the keydb.cfg dated 5/28/2025 11:12PM. Anyone else running into this? MakeMKV v1....

That is precisely my meaning. I'm staring down the barrel of yet another episode of... Error 'Scsi error - ILLEGAL REQUEST:INVALID FIELD IN CDB' occurred while reading '/BDMV/STREAM/00669.m2ts' at offset '31355043840' Failed to save title /BDMV/STREAM/00669.m2ts to file C:/MakeMKV/backup/SOME_MOVIE/...

We've all been there before... trying to back up a disc only to be met with the the dreaded read-error-retry spiral ultimately leading in hash check failure and a handful of missing files. It would be amazing if full disc backup mode presented a choice: Full Disc or Partial backup. If Partial is cho...

All LibreDrive drives have capacity to become riplock-free. This will magically happen some day in future (when time will allow this). ETA is unknown... So, it's been about 5 years. I noticed my BU40N 1.03 is also ripping DVDs at ~2.6x max. Do we have any hope of LibreDrives becoming riplock-free s...
