How To Sanitize A Hard Drive



For non-Solid State Drives (SSDs) I would use a tool like the open source TrueCrypt full-disk encryption. Using the software you want to encrypt the entire disk, including all system partitions, and then change the key to a very long random string. Then format the drive.


If you put sensitive data on a non-encrypted SSD then a good way to physically decommission the drive is to heat it with a propane torch until the PCB catches fire. At that point the magnetic domains aren't magnetic anymore.
