Disk - Clean and Clean All with Diskpart Command

Information
This will show you how to use the clean or clean all command on a selected disk to delete all of it's MBR or GPT partitions, volumes, and any hidden sector information on MBR disks is overwritten.

The data on the HDD is not written over using the clean command like it does with the clean all command below. With the clean command, the data on the HDD is only marked as being deleted instead and is only written over when new data is written/saved to the same location on the HDD next.
ORYou could use the clean all command (secure erase) to do the above and also have each and every disk sector on the HDD written over and zeroed out completely to securely delete all data on the disk to help prevent the data from being able to be recovered. "Clean All" takes about an hour per 320 GB to finish running.

1. In Windows 7, open an elevated command prompt (Administrator Mode), or a command prompt at boot.
OR
2. In Windows 8 and 8.1, open an elevated command prompt (Administrator Mode), or a command prompt at boot.
