Regular disk errors even after reformat!
This seems to happen about once per month, but if I run a disk utility on my MacBook Pro (M1), I get disk errors. They are typically about no anode referencing doc-ids. This is the current one:
Checking the fsroot tree.
error: doc-id tree: record exists for doc-id 270112, file-id 20341051 but no inode references this doc-id
error: doc-id tree: record exists for doc-id 270115, file-id 20358178 but no inode references this doc-id
...
The volume /dev/rdisk3s1 was found to be corrupt and needs to be repaired
...
error: doc-id tree record exists for doc-id 270112, but no inode references this doc-id
Skipped 2/2 repairs of this type in total.
The container /dev/disk0s2 appears to be OK.
This is beyond frustrating. I have reformatted and restored data from cloud backups or physical backups each time, but it is incredibly time consuming. The disk itself has the following properties:
The disk itself is a 4TB SSD with "SMART Status: Verified". But this. Keeps. Happening. I see no explanation for it, but I noticed today that multiple files have gone missing which is a clue something is up.
Is it possible the drive itself is broken??
The only thing I can think of that could cause this is I did connect a failing external drive to it to try to lifeboat some files and it caused the entire laptop to shutdown, fans whir, etc. That corrupted the drive. However, I did a reformat and it was fine for about a month until this started happening again (and again, and again). Each time I reformat and the problem comes back after about a month.
I'm not doing anything unusual on my machine. Is it possible that normal use could cause this? Help?
PS: my spouse has wondered if I have corrupted data somewhere in a file that then corrupts the HD, so restoring from backup --> corrupts the drive again. That doesn't seem to make senes to me, but is that a possibility?
