I'm interested to know if you used mdadm to fail and remove the bad disk from the array when it first started acting up.

No, I should have but left it alone.

I know, my bad.

I was merely interested.

Recently I had a RAID-1 device get marked as bad, but I couldn't see any SMART errors. So I failed, removed, and then re-added the device. It worked for about a week, then it failed again, but time the SMART errors were obvious.

I'd ordered a new drive at the first failure, so I was ready when it failed the second time.

I guess the point is that I've seen "bad" drives go "good" again, at least for short periods of time.
