fsck on umounted disk

If I understand modern disk technology correctly, you should be replacing the disk.

Running fsck on an unmounted disk can correct errors by updating what is usable on the disk, but I do not believe it will make bad blocks good.

If you are seeing bad blocks all the time, the disk is trying to tell you it is on its last legs, and it should be replaced.
