Disk Wipe Freeware by Diskwipe.org

view all images (5) This program is designed to delete entire hard drives with a few clicks, without any chance to retrieve or recover data through other programs.

Disk Wipe displays detailed information about selected device or hard drive (label, filesystem, clusters etc.) and after you click Wipe you will be guided through a step by step wizard. Select new filesystem format because your hard drive will be formatted (NTFS, FAT, FAT32) then choose an erasing pattern (Guttman has 35 passes, is running slow, but is more reliable to permanently delete files)

It may be useful when you want to remove completely any tracks or files from a hard drive or USB stick before selling it.
