Personally I would trust nothing less than a dammed good thrashing 
from badblocks -svw ideally or -svn if the drive has data on it.
Then an smart offline check to be sure the pending/reallocated
sector counts have no increased.

Before commissioning a new drive a do a badblocks -svw atleast 3 
times without any counters increasing (something there are bad 
sectors I just want to flush them out early) then I do some short, 
long and offline smart tests.

Then I add to the array, then I run check a couple of times.

To be explicit:

This would mean to run "badblocks -svn" on md3 or sdb or sdb3 ?

just to make sure I understand you correctly ...

Does that step take long?
