Data Wiping

Don't confused data wiping with 'delete or format data', delete and format your hard disk is simply marks file space as available for reuse, data wiping overwrites all data space on a storage device, replacing useful data with garbage data. Depending upon the method used, the overwrite data could be zeros (also known as “zero-fill”) or could be various random patterns.

Use Write Zeros to drive to zero-fill your hard disk

the steps:

1. Determine the brand and model of hard disk you want to overwrite.
2. Download a CD ISO image or a floppy disk image (depending upon your equipment) and use the image to create bootable media. The floppy disk image is self-contained: run it, insert a blank floppy disk when prompted, and the image is created on the disk. You will need to use a CD burning program that works with ISO images to convert the ISO image into a bootable CD.
3. Restart your computer with the bootable media you created in Step 2.
4. Select the hard disk to zero-fill when prompted.
5. Choose the option to zero-fill the hard disk.
6. When the program is finished, follow the on-screen instructions to shut down or restart your computer.
7. Remove the wiped hard disk; you can now reuse or recycle the hard disk.
