I have now tried to rip "Live Die Repeat"multiple times on two separate Macs and with two different kinds of (self powered) drives and all get the same failure. This is the message I get when clicking on the URL (see attached):

"The IPC error happens when operating system (Mac OS X) suddenly "looses" the Blu-ray drive. Most of the time this happens with external USB drives and is caused by inadequate USB power. Please try using a powered USB enclosure (or powered USB hub) and short USB cables."

I have ripped over 300 movies on these powered drives and only this one has given me this error. It DOES look like there may be some kind of unremovable mark or imperfection on the surface, although very tiny!

And what is the appropriate way to extract this error file and submit it for review?

If you have debug logging turned on (link in my signature tells you how), every time you start MakeMKV it tells you where it is saving the log.

As for the specific error messages, there are some drives that will stop listening to the operating system when they are retrying a failed read, so there will generate time-out errors. It should NOT be giving you IPC or device-not-configured errors, though, unless MacOS has disconnected.

Internal drives should not "run out of power" like USB-powered drives can. Power-related problems usually manifest when the file being ripped is long enough for the drive to speed up. Unfortunately, MakeMKV does not have a "speed limiter" option.

One thing to try as a test is to have the output written to a "slow" destination, such as a ExFAT-formatted USB flash drive. These devices usually cannot write data faster than about 4x read speed, so they'll keep the drive speed in check. If the rip succeeds to the USB flash drive, then the issue is most likely power related.

If it still fails with the speed limitation... the drive is probably fighting to read part of the disk.
