8.1. Security Erase Features
The vendor-specific Security Erase feature quickly erases all selected media on the SSD. The
SCSI vendor-specific (command codes 0xDFh and 0xFFh) or the vendor-specific Security Erase
hardware interrupt (offered as an option upon customer request) activates this function.
When the Security Erase function is activated, all NAND flash (for Full Security Erase, as
described in Section ‎ 8 .1.1), or part of the NAND flash components (for Partial Security Erase, as
described in Section ‎ 8 .1.2) are erased. The SSD Secure Erase option can also be configured to
fill the erased part of the media immediately after the erase process is complete. Bad blocks and
unused flash storage are erased as well.
8.1.1.
When the Full Security Erase function is activated, all NAND flash components are erased.
To make the SSD fully operational after the completion of the Full Security Erase process, the
SSD must be power cycled.
This function is identical to the previously available feature in the SSD product line.
8.1.2.
When a Partial Security Erase is initiated, only selected parts of the media are erased. The
unselected parts of the media remain intact.
The SSD must be power cycled to become fully operational after the completion of the Partial
Security Erase process. Since it is not possible to perform a low-level format on only part of the
media, it is strongly recommended to use the Fill-Format option, as described in Section ‎ 8 .2.
Users can define up to eight areas/partitions on the SSD media. Each area has the following
attributes:



When the Partial Security Erase feature is activated via the vendor-specific security erase
hardware interrupt and the partial Security Erase is set to ON, only those partitions with the To
Be Erased flag set to 1 are erased.
When the Partial Security Erase feature is activated via the SCSI vendor-specific command, the
user may select whether to erase the designated partitions, or whether to override the designated
parameters and set different partitions to be erased.
When a sector resides in overlapping partitions where one partition is set to be erased and one is
set to remain intact, the partition plus the part of the sector that overlaps will be erased.
