This program can check your disk for bad blocks, using very little
memory and fast. There is almost no other piece of software that scans
a disk as fast as this program. Usually, no bad blocks are found, and
after the scan there is nothing you can do. If bad blocks are found,
you are given the option to remap them, that means telling the disk to
substitute new blocks for them without the need to reformat. But
(isn't there alwaysa big but), the data that once was contained in the
blocks gone bad can't be read anymore. That means that the file the
bad block was in, is damaged.
