[Discuss] ATA Access Errors For Spinning Disk

[jbk]

I periodically get access errors for a specific spinning 
disk that I have done these things to diagnose:
Changed Sata Cable
Switched Sata bus on MB
Run E2fsck on the 3 formatted ext4 partitions w/ no errors found
Run smartctl -a: all results within norms
Run smartctl -t short: No errors found

Disk operation age is about 7.5 years with around a couple 
hundred starts. It has been in continuous operation for over 
8 years except during vacations. On occasion the disk 
partitions will become unmounted and a mount -a will remount 
the partitions as a different device from lets say sda to 
sdd. I've not lost any data and I do regular backups to 
another device that's rotated out of system.

I seem to have always had these errors present on this MB 
that is maybe 4 or 5 years in operation. Any thoughts on the 
cause of this issue? Do others see this behavior on occasion 
on systems they manage?

On this same system my Rocky OS on an SSD is showing no 
issues at all. Same operation age as the spinner.
