All the drives I've seen mark bad sectors as "pending reallocation", they they return read errors on that sector unless they manage to jag a good read, in which case they then reallocate the sector. Or else they wait for you to write to the sector triggering a reallocation. There may be drives less well behaved out there, but I've not come across them.
