I have an HP laptop with a Toshiba hard drive. When booting up the laptop keeps blue screening. I have run multiple hard drive tests from UBCD and the laptop and the hard drive passes. I put the drive in an external case and after a slow process I can see the folders ion the drive but cannot access them. On the hard drive test, it says the "Security Freeze Locked". Whjat can I do to be able to get necessary documents off this drive? THe laptop is running Windows XP
