If a disk has one or more bad sectors, surely the only logical action is to schedule it for replacement as soon as a new one can be obtained; and if it's still in warranty, send it back. If the data is valuable enough to warrant use of RAID (along with, presumably, appropriate backups) surely it is too valuable to risk continuing to use a known faulty disk? In which case, I would suggest that dangerous experiments that try to force the disk to reallocate the block are arguably pointless. Just my opinion, but one that has served me well so far. Regards, Geoff.
I would be surprised if you got warranty replacement just for a few re-allocated sectors. The sheer quantity of sectors in modern drives and the tiny magnetic domains involved means **no** drive is error-free. Just most defects are identified and mapped out before shipping. Reallocations cover the marginal cases.
I replace drives when re-allocations hit double digits, though I've had to run a few corners cases well past that point.
