Fragment your harddrive to test the perfomance of disk defragmenters. Fragger has been created to test the effectiveness of disk defragmentation applications by creating a very large amount of fragmented files on user-selected drives.

Fragger can put Windows, its I/O system, and associated disk I/O hardware under considerable strain and should only really be used on healthy hardware.
