File system verify or repair failed. : (-69845)
It is impossible to run a Samsung QVO 870 8 TB on Monterey.
I tried all file system types, APFS and HFS+, first it works for a while, then suddenly the disk may no longer be mounted.
This is indicated by error message such as "Could not mount “Manual Bkup 8TB”. (com.apple.DiskManagement.disenter error 49244.)"
Using Disk Utility's First Aid, is ending in "File system verify or repair failed. : (-69845)".
I tried all other forum/discussion.apple.com suggestions I found, nothing helped.
There must be a severe bug in the File System handling of newer macOS versions.
The disk I'm trying is the 2nd one, the first I already returned.
I tried on a MBP16 of 2019 and a iMac 5K Late 2015, both running Monterey 12.2.1.
