SSD Secure Erase

by

Before secure release, it must not be frozen. Can use the following command to keep track of status of drive.

hdparam -I /dev/drive

Look for frozen in output:

Security: 
       Master password revision code = 65534
               supported
       not     enabled
       not     locked
               frozen
       not     expired: security count

If still frozen, attempt hybernation/reset

echo -n mem > /sys/power/state

Set password

Need to set password first

hdparm --user-master u --security-set-pass password /dev/drive
