Removing Hard Drive Password When Locked

I have a 2.5in hard drive that came out of a cartridge for a Dell RD1000. It has a password on it that is disabled whenever the drive is used with its USB component; however, if I try to boot up with it directly connected to my computer, it will ask for a password. I do NOT care about any of the data on it, but I would like to be able to use the drive as a SATA drive. I do not know the user password for it, so using hdparm --user-master u --security-erase PASSWD /dev/sda does not work. I cannot unlock the drive (from my knowledge) because I don't know the user password. I'd really appreciate any thoughts you guys have! It would be simplest for me to implement a solution with a linux program, but if necessary it's I suppose I could use windows.
Thanks!

Below is the output of hdparm -I /dev/sda

Evidently UBCD has a program on it that is supposed to bypass or disable ATA passwords. Something like ATA lockout tool. So if you have an ultimate boot disk, or can write one, you might be able to do it with that.
