Version: restic 0.18.0 compiled with go1.24.1 on darwin/arm64
I’ve been backing up my data to two separate NAS drives using Restic for a while and I’ve also restored files successfully in the past. I can’t remember ever having gotten errors when backing up. I recently decided to do a full check on the backup using restic check --read-data. This give A LOT of errors, for example:

I tried restoring a couple of files at random and they were fine. My hard drives are old but the NAS says they are healthy. I’d like some help figuring out what caused the errors, the drives, the NAS or restic. I don’t use the NAS for anything but backups so I’m considering getting a HDD dock or replacing the drives with a NVMe drive.
The hard drives are 3 TB each and have 13% free disk space.
UPDATE: I ran restic repair snapshots --forget which replaced a number of files with empty directories. Now running restic check --read-data again, which will take a while. Already getting errors like
