Error 'Scsi error - ILLEGAL REQUEST:INVALID FIELD IN CDB' when reading 4K UHD BluRay

[bryanvh]

Hi everyone. I've found other threads about errors like this but they're generally old and lacking answers and I didn't want to necro one of those.

I'm getting these errors all of a sudden when trying to rip a UHD Blu Ray. The Blu Ray drive has been acting fine ripping other Blu Rays, even UDH ones (LibreDrive firmware properly installed and UHD support enabled and working). So, this almost suggests it's a disk specific issue. But, the weird part is that it's just one disk in a box set of LoTR so I can't imagine why the others are reading fine and this one isn't.

Error 'Scsi error - ILLEGAL REQUEST:INVALID FIELD IN CDB'
and
Error 'OS error - The specified request is not a valid operation for the target device'

I'll attach the log from the rip. But, I'm sort of at a loss. Is there anything to try or anything that stands out as a culprit based on the logs? Thanks in advance and sorry if this is just basically chasing gremlins.

Start by cleaning the disc, even if new.

Thanks! I wouldn't have through that new disks would have needed it. I cleaned it and the error moved from ~4 million position to ~8 million position, but it still failed. Played with it a lot more, including a few more cleanings, but this thing was determined to fail no matter what.

Guess it was just a bad burn on the manufacturing side. Woo for statistical possibilities. Haha

"New disks" is relative. I've found it more frequent that disks that were released 6 months ago have acquired a film from their packaging that prevents "error free" reading, and it needs to be cleaned off.
