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

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.

VERY early research and tests for a disk scanning core.
