I'd like to wipe a stack of drives (spinning and SSD) securely. I'm familiar with the ATA Secure Erase (SE) command via hdparm, but I'm not sure if I should use the Security Erase (SE+) command instead.
There is some evidence that these commands don't work on all drives. How can I ensure the drive is really wiped, including reserve areas, reallocated sectors, and the like?
I'm planning to use a linux live CD (on USB). Ubuntu provides a workable live CD with which I can install hdparm, but is there a smaller live CD distro with updated software versions I should use instead?
So, in summary:
What are the pros and cons of SE versus SE+?
How can I ensure the drive was truly and thoroughly wiped?
Which linux distribution should I use?
