Disk surface background scan tool. It slowly reads the whole surface of a given physical disk and then repeats indefinitely. When the disk encounters a weak sector during the read operation, its firmware will hopefully relocate the data in this sector into a good spare sector.

DRCHECK (Disk Routine Check) is a disk DOS-level surface scanner

VERY early research and tests for a disk scanning core.

Scans the specified disk and tells available storage information in GB and does not use modules while doing these but runs on Windows operating systems.
