Memory Sanitization and Removal Procedures

This section explains how to clear, sanitize, and remove memory from your
instrument, for all types of non-volatile memory that can be written to during
normal instrument operation.
Table 5-1 Disk Drive
Description and The Disk Drive is the main memory for the instrument. It has very large storage capacity, plus fast
purpose read and write times. There are no limitations on the number of read/write cycles.
It contains the Operating System, Instrument Software, Factory Calibration Data, Diagnostic
software, Crash recovery image, user instrument states, user data files, user trace data and any
user-installed third party software. The Disk Drive is written to frequently by the Operating System
and other application software.
Size 80 to 256 Gigabytes
Memory clearing Software utilities are available that comply with the clearing requirements specified for Magnetic
Disks and Flash Drives in the "Media Sanitization Matrix" in Appendix T of the
Service (DSS) Assessment and Authorization Process Manual
Memory We recommend always removing the Disk Drive to achieve sanitization.
sanitization
For program classifications lower than Top Secret, this media type can be sanitized using method
"d" as defined in the "Media Sanitization Matrix" in Appendix T of the
(DSS) Assessment and Authorization Process Manual
For Top Secret and higher program classifications, Disk Drive removal is the only acceptable
sanitization procedure.
Memory removal See the Chapter
Write protecting The Disk Drive cannot be write protected. The operating system and software must be able to read
from and write to the drive during normal operation.
Memory The Disk Drive memory can be validated using third-party Windows utilities.

Table 5-2 EEPROM Memories
Description and These memories are used to identify the assemblies (header info) and store option configuration
purpose data. Some are also used to hold factory software for FPGAs. The software is loaded when the
instrument powers up. This memory cannot be written to during instrument operation.
Size 2 kbit to 8 Mbit
Memory clearing Not applicable. This memory does not contain user information and is not accessible by the user.
