    Intel 510 SSD and secure erase

    brylant

      Hi,

       

      Hi,

      I'm trying to follow Secure erase instructions (https://ata.wiki.kernel.org/index.php/ATA_Secure_Erase) but I run into a problem I can't  really figure out.

      I have 2011 iMac, I installed intel 510 ssd and  trying to do secure erase (in order to install/reinstall lion). Here's  what I do:
      1. boot ubuntu (11.04, x86). booting from live CD.
      2. run: hdparm -I /dev/sdb. Here's what I get:

      Security: 
             Master password revision code = 65534
                     supported
             not     enabled
             not     locked
                     frozen
             not     expired: security count
                     supported: enhanced erase
             2min for SECURITY ERASE UNIT. 2min for ENHANCED SECURITY ERASE UNIT.

       

      3. put iMac to sleep and run hdparm again:

       

      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.

       

      And this is where the problems begin...
      4.

       

      hdparm --user-master u --security-set-pass passwd /dev/sdb

      /dev/sdd:
      Issuing SECURITY_SET_PASS command, password="passwd", user=user, mode=high
      SECURITY_SET_PASS: input/output error

       

       

      I tried --user-master m, secure erase with NULL password etc... Nothin  works. I _always_ get input/output error regardles of the command...
      I'm using latest hdparm (9.37 compiled from sources)
      Any idea what is wrong? I don't really want to tear the iMac apart again to disconnect the drive...

      Thanks,
