4K No Country For Old Men - Rip consistently fails with 15 seconds left

[CalKing]

Hello Everyone,

I've repeatedly attempted to back up 'No Country For Old Men' 4K this week, but it consistently stalls near the end. The backup progresses smoothly until the final 15 seconds, when the read speed drastically drops from 22 MB/s to 150 KB/s and lower, making the remaining time estimation continue to increase a few seconds at a time. This ultimately leads to a complete stall/fail. I've successfully backed up other 4K discs, so the problem seems specific to this title. Any thoughts as to what is happening?

You could try to gently clean the disc.

Also, if you have a different optical drive to try that might help too. Personally, I've found my Pioneer drive to better than my LG drive with triple layer UHD discs.

Thanks for comment.

I had previously cleaned the disc twice with soap and water. This time around (after seeing your suggestion to clean it) I decided to take things up a notch and used rubbing alcohol - it worked!
