Yep I saw that post and followed it right through to the end but it didn't help. It looks like it didn't help the original poster either.
I followed the recommendations.
#1 USE HDDerase version 3.3 (but I tried both 3.3 and 4.0)
#2 Prior to booting PC unplug power from the SSD but keep the data plugged in
#3 Start PC and wait for DOS to boot via USB or CD (I used USB after killing a few cd's with DOS boots that didn't work)
#4 At the A:/ prompt plug the SSD power back in
#5 Run HDDErase
It ran, recognized my drive (on P0), tried to wipe, tried to unlock, tried 2 known passwords, but didn't succeed only giving me the same options as in the other post:
If selected drive is locked with a non-HDDerase password the user is given the
option to: 1) unlock with user password, 2) unlock with master password (if high
security), 3) secure erase with user password, 4) secure erase with master
password, 5) enhanced secure erase with user password (if supported), 6) enhanced
secure erase with master password (if supported). If option 3, 4, 5 or 6 is
selected any possible HPA and/or DCO areas will not be reset.
I had bios set to IDE (with compatibility not enhanced) prior to running HDDErase and it wasn't set to ACHI or RAID. I wish I knew how this thing got locked.
