Disk Disabled, but preclears show no issue. Thoughts?

[RealActorRob]

Had a parity disk disable due a read error (forget the exact problem) but subsequent preclears are going fine. One completed, another almost completed, plan to read 3.

 

Speaking of, is there a way to test R/W a particular sector say, 50 times?

 

Thoughts on using it? Probably use it as a Chia drive but might press it back into service if it passes a bunch.

 

Also: I've got a drive pushing 93,000 power on hours but only 110 start/stop counts. It's at a nice 35C now.  WD20EARS.

Unraid disables a disk whenever a write to it fails for any reason because the failed write makes it out of sync with the array and it has to kick it out.

 

Connection problems are much more common than disk problems.

 

Probably no way to know what happened since you have no doubt rebooted since then, but you could post diagnostics if you want us to take a look at SMART for the disk.

 

Preclear is too much trouble to go through unless you are really just trying to get the disk past infant mortality. If it has survived for a while then there are better ways to decide if it is still OK.
