#MAC DISK UTILITY REPAIR FAILED ALREADY UNMOUNTED HOW TO#
So with a couple of days of research, the only conclusion I came to, was that it's somekind of a bug/feature between APFS, BigSur, TimeMachine and SMB sharing: seems like BigSur introduced some big changes in the APFS encryption and security model, which TimeMachine knows how to handle, but SMB sharing is still behind it, and I guess that DiskUtility is as well.

Plugging in the disk locally works as a charm, but it's another manual action you have to do, and tend to forget about it :) My case is that, I really loved it with Catalina, when my mbp started backuping over network automatically every time it happened to be in the office, and I had no intervention into that.

I also have a suspicion that this one is a bug. (probably running in system permissions)Ħ) I try to share the drive over SMB for my macbook to do the backups - I receive an error that I do not have necessary permissions (macbook tries to connect in my permissions under my username)ħ) Endless trying and experimenting with permissions - it still shows that I have read-only access to the drive (nevertheless local backups from iMac complete without an error)Ĩ) Remote backups via SMB do not work - argues that I do not have necessary permissions.ĩ) When I try to run the disk utility on the drive - I get the error you describe above.īackups on Catalina were working just fine.

(I'm a full admin locally) But time machine backups locally complete without a problem regardless of that. External drive - brand new LaCie external SSD 2Tb, bought yesterday.ġ) SSD is attached externally via USB3 to iMac.Ģ) Reformat the drive to APFS Case sensitive encrypted.ģ) Set up a time machine - first backup from iMac locally completes without errors, no problem at all.Ĥ) All next backups locally are also fine, even after restart.ĥ) When I restart or detach the drive from my iMac - I see that the drive shows me weird things, that I have only read-only permissions on the drive.

My use case - 2017 iMac 27, running BigSur latest updates, and a 2020 MBP Pro running also BigSur. When I do Disk Utility First Aid on the top level SSD drive it passes without error, and every other partition passes without error (just the APFS Time Machine Partition fails). How many partitions do you have on your disk? This particular SSD I am using has quite a few: I'll leave it for now, but not very comforting. Then I tried the first aid again after ejecting and remounting the disk and got the error code 66 again. After the initial backup completed I tried the Disk Utility "first aid" on it and it completed without error. What I did after receiving the error was format the partition clean (not the whole drive) and I did a fresh Time Machine backup. My Time Machine partition (APFS encrypted) is getting the same "failed to enable crypto I/O mode for container" exit code 66. I am having the same issue with my SanDisk Extreme Pro SSD.
