I have an external hard disk (2TB) with 2 container disks. There is an APFS volume on each of them. Recently, one of the two disks can no longer be mounted. Unfortunately, my data is on this one, and I used the other one for the Time Machine backup. But this one is mounted and appears on the desktop. I've tried all the tips I could find, but so far without success. Can you help me?

I had this happen 4 TB WD My Passport on Big Sur 11.6.2, the 1 TB partition for my Time Machine didn't come up and mounting gave the "disenter error 49218". Here's what worked for me (at least for now):
com.apple.DiskManagement.disenter … | Apple Developer Forums "Try to mount the disk, and switch to Terminal and write sudo pkill -f fsck"
Attempted to run First-Aid on that partition.
Restarted the computer.
Time machine came back after that. No clue which of the steps may have actually fixed it. Will find out the next time that this inevitably occurs.
