How to clean a hard drive from any and all partitions
Do you have a hard drive with a partition inside that will not go away? Connect the hard drive to a PC and go into the CMD (command prompt) mode.
Type in "diskpart".
Type in "List disk".
From the list, select the drive you wish to clean by using a command like "Select Disk 4"..
Type in "clean".
The disk will be void of all formatting and partitions.
