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.
