I don't know what to tell you. I was able to disable security on the Stock Z1 hdd on my Dell Optiplex GX 270 with no problems.
Did you accidentally put the drive in the Z1/Z2? "even a drive you paid for seperately will be locked if inserted in the Z1. The drive doesn't even have to be setup to work in the Z1 to be locked. " If the drive is locked, you won't be able to access it in any way until it's unlocked. $45
If it's not locked, it's possible that it's not a supported drive, or that it's been damaged. First make sure you meet the requirements:
