hi,
want to ask, how to perform a Secure Erase using hdparm from a linux boot medium. I'm using a Macbook Pro.
I've already done that many times with a Intel SSD Postville G2, never had a problem performing a Secure Erase.
But with the new 320 series, it just won't work. I can't set a password by using the command:
hdparm --user-master u --security-set-pass pwd /dev/sda There's no error message or anything like that. It just takes some seconds.Here's what i get after trying to set a password:
Security: Master password revision code = 65534 supported not enabled not locked not frozen not expired: security count supported: enhanced erase 2min for SECURITY ERASE UNIT. 2min for ENHANCED SECURITY ERASE UNIT.It shouldn't output "not enabled", right? "enabled" would be fine?
Hope anyone is willing to help me, thanks a lot in advance!
I really appreciate it.

hi,
thanks for your help, I appreciate it.
As I said, I've done this several times with the G2 Postville 80GB SSD. Worked flawless.
It's /dev/sda for sure. The problem seems to be setting a password, which I can't. See Step2: https://ata.wiki.kernel.org/index.php/ATA_Secure_Erase https://ata.wiki.kernel.org/index.php/ATA_Secure_Erase and my 1st post.
Maybe it has something to do with this new AES feature?
I don't get any errors, nothing. The secure erase command took about 7min, was about 50s with the G2 SSD.
Any other ideas?
Thanks!

So when you say it took 7 min.. You actually got it to do a secure erase on the 320 series?

exactly.
As I said, I'm able to type any command, which is necessary. And I don't get any error outputs.
The final secure erase command took about 7mins, but after it's finished, i look after my partitions with gparted and
everything is still there, all files etc. MacOSX will just reboot, as if nothing happened, just weird.

I installed my 320 today and tested it out and performed a secure erase sucessfully. I am assuming you are using Unbuntu via a CD to do this? Did you remember to type Sudo su before you did anything.. Also when I performa secure erase I pop in the Apple CD and erase my SSD first. Try that! let me know!

will definitely try your suggestions, thanks. I'll let you know, as soon as possible.
btw: which mac are you using with your Intel 320 SSD? And how long does it take for you to secure erase your SSD?
