4.6.1.3 Sanitize Interrupt
The Sanitize Interrupt command has the following characteristics:
The SSD receives the Sanitize Interrupt at any time.
The Sanitize Interrupt initiates the immediate execution of the default Sanitize procedure.
The default factory-preset Sanitize procedure is to erase the entire media and leave it empty
(to perform the Security Erase option).
If unit is powered up with Sanitize Interrupt active, the default Sanitize procedure is
launched immediately.
If the Sanitize Interrupt is still active upon completion of the default Sanitize procedure, the
SSD restarts the default Sanitize procedure. This cycle is repeated indefinitely for as long as
the Sanitize Interrupt command is active.
Note: Please contact the SanDisk sales offices for information regarding the available hardware
Sanitize Interrupt options.
4.6.1.4 Auto-Resume Sanitize Feature
When Auto-Resume is enabled (the factory default setting), if a power interruption occurs during
a Sanitize procedure the SSD restarts the Sanitize procedure on the next power-up.
If the Sanitize Interrupt command is active during power-up, the unit first completes the Sanitize
procedure that was initiated before the power interruption. If the Sanitize Interrupt command is
still active when the procedure is complete, the SSD relaunches the default Sanitize procedure, as
described in Table 10.
4.6.1.5 Random Data Written During the Sanitize Procedure
The random data used to overwrite user data is a digest of pseudo-random generation and real
random data. The pseudo-random generation is seeded in such a manner that even if the SSD
launches the Sanitize command under identical external conditions (for example, if the unit is
powered on with Sanitize Interrupt active), it will produce different seeds and different
pseudo-random data.
4.6.1.6 LED Activity During the Sanitize Procedure
During the Format and Sanitize procedures, the red LED provides the following indications:
a.
Remains lit during the Erase phase (for the Sanitize procedure, during each erase phase)
b.
Blinks during the Media Fill phase (for the Sanitize procedure, during each fill phase)
c.
Remains lit for a short period while the disk achieves ready status after completing the
Sanitize procedures.
4.6.1.7 Using the SSD After a Sanitize Procedure
After a Sanitize procedure, if the fill option is not activated, the user must perform a low-level
format on the media. Failing to perform the low-level format may result in a longer start-up time.
