This utility is designed for people who have faulty drive and want to transfer the data directly to another drive without doing a file by file copy. This saves the need for operating system re-installs and allows drives with an unknown file system to be copied (including from console game machines, data recorders, Mac etc). The program has a built in data recovery function which will attempt to recover data from bad sectors to ensure all the available data is restored from the drive. This program is designed to run under NT/XP/2000 or later operating systems. It will run under windows 95/98/Me operating systems but only windows logical drives can be copied.
• Erase Free Space  SDelete overwrites deleted file's on-disk data using techniques that are shown to make disk data unrecoverable, even using recovery technology that can read patterns in magnetic media that reveal weakly deleted files. You can use SDelete both to securely delete existing files, as well as to securely erase any file data that exists in the unallocated portions of a disk (including files that you have already deleted or encrypted). SDelete implements the Department of Defense clearing and sanitizing standard DOD 5220.22-M, to give you confidence that once deleted with SDelete, your file data is gone forever. Note that SDelete securely deletes file data, but not file names located in free disk space. It must be run from the CMD with the following parameter: PATH>sdelete.exe -c F: or c:\users\bear\desktop\sdelete>sdelete.exe -c F: where F is the letter of the drive you wish to attack. SDelete is set by default for 1 pass which is good enough according to current belief.
• Erase Hard Drive/Partitions/Folder/Files  Hardwipe is a free file wiper and drive cleaner for Windows. It can be used to permanently erase, or to "hard wipe", data on disk and portable storage media (i.e. USB drives and memory sticks) in order to prevent personal or sensitive business information from ever being recovered.

• Erase Hard Drive  DiskWipe will erase all disk data on any partition and prevent recovery of that data. Formatting a hard drive with the regular method leaves the possibility open to recover data from that partition. Disk Wipe uses powerful algorithms which fill the volume with useless binary data multiple times making it virtually impossible for anyone to recover any data from that disk. You cannot wipe a partition you have mounted such as the operating system you are logged into, so you should access that partition from a dual operating system which is installed on another partition or disk drive or computer. You can install Disk Wipe on a bootable CD, boot to it and erase your active partition from that. Portable. Size: 966 KB. Win XP/Vista/7/8. 32/64bit.

To securely overwrite free space on your computer (no external program needed.) simply click on your Start Button / All Programs / Accessories / and right click on Command Prompt and choose Run as Administrator.

When the command prompt opens type: cipher /w:C (where C is the letter of the drive you want to securely overwrite the free space on.)

It will overwrite the free space with three passes. First with all zero’s – 0×00. Second with all 255’s, – 0xFF. Finally with random numbers.

It took about 25 minutes to overwrite 50GB of free space on my system.
