SSD Data Destruction Several commercially available software programs exist
to completely destroy all data on a data storage device such as the SSD. DoD
5220.22-M is a software based data sanitization method for total data
destruction. The DoD 5220.22-M sanitization method was originally defined by
the U.S. National Industrial Security Program (NISP) in the National Industrial
Security Program Operating Manual (NISPOM). The process involves overwriting
existing information on the SSD (or other data storage device). Typically, this
means writing a 0 (zero) to every addressable location on the device, verifying the
write, writing a 1 (one) to every addressable location and verifying the write, and
then writing a random character (in some cases writing a 97) to every
addressable location and verifying the write. Using a DoD 5220.22-M sanitization
(or a variant) prevents all software and hardware based data recovery methods
from obtaining information from the SSD.
SSD Removal Because it is virtually impossible to completely and selectively
erase all user data on a hard drive without also destroying the operating system,
the best method for maintaining security when the controller must be removed
from a secure area is to remove or replace the hard drive.
1 Turn the PXIe chassis off.
2 Remove the controller from the PXIe chassis.
3 Remove the SSD drive. For instructions on removing the SSD drive, refer to
“Replacing the Hard Drive” on page 60.
