Description
All addressable locations are overwritten once with random
characters.
User and "Secure Storage" partitions on CPU flash are erased
by flash vendor firmware. For algorithm details, see the
Application Note Greenliant NANDrive Security Erase Feature,
Purge Command Specification.
User data is erased with flash chip block-erase commands. No
overwrite is performed. During erasure, the system files are
temporarily moved to main memory and are then restored to
CPU Flash when erasure is complete.
The file system is formatted, then all addressable locations are
overwritten with random characters, and then the file system is
reformatted again. These actions are then repeated.
All addressable locations are overwritten with a random
character three times.
Erased by drive vendor's firmware, which erases user data area,
SSD reserve area, and retired blocks.
The firmware accepts and implements the ATA commands
SECURITY ERASE UNIT and ENHANCED ERASE MODE. For
details of these commands, see
Command Set (ATA8-ACS).
All addressable locations are overwritten with a random
character three times.
