Whats a good checklist of things to check outside of a software or hardware error for 4k rips/ backups that fail

Clean disk
Restart drive
Restart software

Having issues with a star trek 2009 disk that should work, every other disk does. There are a few scratches but not many.

Anything else i should get in habit of checking before posting logs or reinstalling software?

UHD disc with scratches is dead for ripping.
you can try polishing them out that might make it work but you need a perfect disc

Heres the logsince ive exhausted other options.

Yeah that's a read error try polishing the disc with some disc compound and then polish.

Or just get a replacement

Thanks!
