capabilities. The commands are similar to disk formatting commands and do not provide sector level data
overwrite. These erase commands are not recommended for securely removing customer data.
These commands are only accessible from the device pre - boot menus.
 Clean Disk removes all data from the disk. This command will render the device inoperable. The device
firmware must be re-installed to the disk before the device can be used again.
