The write > check on most hard drives is very simple and consists only of parity. actually it's a far more sophisticated ECC like code that even allows single bit errors to be automatically corrected. And disks do constant "signal strength" measurements and such and relocate sectors before things go bad. Remember that before using a sector on a new partition, you *always* write to it (in a filesystem at least), and that's where the bad situation will be detected *and remapped*. If your disk is beyond remapping, the smart daemon (on by default) will send you a nice mail saying that your disk is going bad.
