</div>fsck means nothing. Use mkfs with badblock check. Unless you low level<br>
formatted it, nothing is done about bad sectors. Of course modern drives<br>
don't need that since they can automatically map bad sectors _on_write_<br>
(not on read). Writing to the whole disk should help the drive remap<br>
all bad sectors.<br>
