I have been using MakeMKV version 1.12.0 to backup and make mkvs of a number of BlueRay disks that I have. If I am present when the operation is complete, I can click OK, then eject the disk and start another one without trouble. However, if I am away from my computer when the operation completes, it seems that sometime later the Blueray drive becomes invisible to the system - showing as unknown in the system report. MakeMKV will still list the drive in the selection menu, but it is impossible to eject the disk, nor is the disk mounted in Finder.

So far, the only way I have found to recover from this situation is to cold boot the system (i.e., shutdown and start), a warm boot (restart) does not cause enumeration of the SATA tree.

System report shows the following in this situation:

Intel ICH10 AHCI:

Vendor: Intel
Product: ICH10 AHCI
Link Speed: 3 Gigabit
Negotiated Link Speed: 1.5 Gigabit
Physical Interconnect: SATA
Description: AHCI Version 1.20 Supported

Unknown:

Native Command Queuing: No
Detachable Drive: No
Bay Name: Lower

While MakeMKV shows:

Current profile: BD-ROM
Manufacturer: HP
Product: BD Writer bd340i
Revision: RH26
Serial number: 3772512006 216042500578

No disc inserted

The log of operations completed before this situation occurred is:

That happens to me on occasion also. I have become accustomed to quitting and relaunching. It is not limited to Blu Rays it does it also with DVDs.

Me too, but slightly different. MakeMKV struggles to eject the movie, but desktop shows disc as mounted.

But the WORST part: the disc keeps seeking after it's completed ripping, light keeps blinking, and when I finally get the disc out, it feels VERY warm. I'm afraid it's damaging my discs.

Can we please fix this? Maybe an "auto-eject on completion" option to avoid overheating the discs. I know optical media isn't impervious to heat damage.

The first step in "fixing this" will have to be figuring out whether it's MakeMKV doing it or not.

I do not know what the Mac equivalent of the Windows Task Manager is, but, when this happens, is MakeMKV showing up in the task display as using CPU time? If it is, does killing that task "release" the disk, and allow MacOS to see the drive again?

Good point. It's possible macOS is trying to access the disc. I'll let it happen and use Activity Monitor to see if it's MakeMKV or not. Also I should mention it only seems to happen with the Asus BW-16D1HT 3.00 and not with the other drives I've used.
