Recovering a drive question

So I had a drive that appeared to go south on me. Swapped it out with a new one and rebuilt the array, but since I had an open slot I put the old drive in intending to try and see if it was really bad. Since I haven't been paying attention I didn't realize that preclear is screwy right now (or so I gather). When I try and use Unassigned Devices I get this:

 

bad superblock on /dev/sdb1

 

The drive shows as xfs and really all I want to do is format and stress test it. What's a good option to do that with now?

So the test completed fine:

So... what do I do to recover this sucker? Do I just need to reformat it or something?
