So, I have this WD2000JB IDE disk... I thought I would put it in my XBOX. I prepared it for the XBOX, then I was about to lock it with the HDD key I needed. While it tried to lock it, it somehow failed (I got ATA command failure or so)... Tried to lock it again, but it was already locked

However, the key it is locked with is not the same, the XBOX refuse to boot it.
Then I tried to unlock it quick (with the same password), but it wouldn't unlock it... Then I rebooted and tried again, same error.
I got mad, and tried several tools like mhdd and hdderase. Not even "WDCWDCWDCWDCWDCWDCWDCWDCWDCWDCWD" as master key is working... How can I fix this shit? I don't mind if I have to wipe the whole disk, I just have to get it unlocked so I can format it again

I heard about this "ATA Terminal", how does it work? What cable do I need? I tried to search a bit, but couldn't find anything...
