You can try to force a drive to remap bad sectors by wiping it, e.g. with DBAN or badblocks, but that means removing it from your pool, at least temporarily.
In fact you can do it without wiping it by using dd to write only this sector but it's not something I'll recommend to a noob however...
There is a small possibility of data leakage, so if it's a real concern, wipe it before returning it.
Hum... only one drive from a pool? I don't think you can recover much (as we sadly see each time a member has a problem with his pool and want to recover the data...).
