SSD Data Destruction Disk
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 O (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 and Installation
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.
Power off the PXIe chassis. You do not need to remove the M9037A
controller from the chassis to replace the SSD.
2.
Loosen the two thumb screws securing the cover to the controller’s front
panel.
3.
Unseat the removable SSD with its mounting bracket from the connector
and pull straight out.

Electrostatic discharge (ESD) can damage or destroy electronic components. All work on
electronic assemblies should be performed at a static-safe workstation. Refer to the
documentation that pertains to your instrument for information about static-safe
workstations and ordering static-safe accessories.
