1. Click Start, type “cmd”, right click the program and select Run as administrator to get into the Command Prompt.
2. In the pop-up window, input “format f:/fs:NTFS/p:1” and hit Enter to write zeros to every sector of the drive once
● “f” is the drive letter of the partition on the hard drive that you want to wipe, you can change it based on your own situation.
● A single pass of zeros to a hard drive can prevent all software-based file recovery applications from extracting information from the drive. To be safer, you can replace p:1 with p:2 to do two passes of zeros. If you want to format or wipe the drive that holds running Windows 8, you can insert Windows installation CD/DVD to your computer, enter BIOS to boot machine from the CD/DVD and then go to System Recovery Options window and choose Command Prompt to do steps that mentioned above.
