Ok, for background, I recently replaced the HDD in my Thinkpad with an SSD. I had previously had it set up with a password to unlock the HDD, but it required a user-level password to actually use it, and a manager-level password to change anything. Of course, since the user-level was the only one I ever used, I have completely forgotten what the manager-level password was...and that's the one that I need to remove it.
So, my question. I don't need any data off the drive, I just want to blow the whole thing away and start from scratch. Unfortunately, because of the password lock, I cannot actually access it. It does, however, appear as a device in Linux, though I cannot do anything to it because of the lock. I feel like I should be able to blow it away since Linux has direct device-level control, but I cannot for the life of me figure out how.
Any ideas?
