I did a search and I'm coming up blank on DDG and here. Maybe someone can help me get to the bottom of this.
I have a couple of 512Gb Samsung T1's that I've converted, or partly converted, to APFS and I'm seeing strange errors when I try to run First Aid (or the command line equivalent fsck_apfs -y /dev/diskxsy).
The disks themselves seem to function fine. The disk/media passes checks and so do the volumes (APFS encrypted). If however I try to run the First Aid on the container in the middle then I see: -
Repairing storage system
Performing fsck_apfs -y -x /dev/disk4s2
Checking volume.
Checking the container superblock.
Checking the EFI jumpstart record.
Checking the space manager.
Checking the object map.
Checking the APFS volume superblock.
Checking the object map.
error: mount_apfs exit status 73
The volume /dev/disk4s2 could not be verified completely.
Storage system check exit code is 78.
Storage system verify or repair failed.
Operation failed…
Running the equivalent on the command line we see an extra error (bolded): -
$ sudo fsck_apfs -y /dev/disk4s2

mount_apfs: mount: Unknown error: -536870206
error: mount_apfs exit status 73
** The volume /dev/disk4s2 could not be verified completely.
The disks were converted from File Vaulted HFS. One has the entire 512Gb dedicated to data with encrypted APFS and the other had a 256/256Gb split across Time Machine and CCC (yes, I know I've lost my local backups if I lose my disk. They're just for different forms of recovery
) with obviously only the CCC volume being APFS and the TM one remaining HFS+
I'm not seeing the same error on a germanently inserted JetDrive Lite, though I haven't encrypted that. I haven't yet checked if my internal drive/volume suffers the same issue.
Could someone check if they're seeing this behavior on external drives? Especially ones that are a) converted b) encrypted, c) SSDs, d) Samsung T drives?
Thanks!
