Hacking Truths: Create Bad sectors on hard disks

Create Bad sectors on hard disks

This program will create bad sectors on the hard disk. If you left it running for long enough, it could render a hard disk quite useless. When bad sectors are found, the sector is marked as bad, so fixing the hard disk is not an easy task. Unless the victim has time and knowledge to fix the disk, the hard drive can be left quite literally defective.
