If you can enter the bios setup you can disable it there. The bios password is usually easier to crack if set than a hdd lock. If it is a Windows password search for a bypass for that on google. If it is a hdd lock than depending on the manufacture of the drive it may have a master password that can be entered using atapwd.exe. If the hdd password is set it goes with the drive and can only be unlocked with a password. No swapping or disconnecting or shorting will unlock it. It's like putting a combination on a piece of paper and locking it in a bank vault, unless you know the combination you can't see the combination or unlock it. If all else fails than these guys can help for a fee, http://www.hddunlock.com. Hope this helps.
