|If this is a drive locker done by the BIOS then you don't. I have tried with an HP and not even their tech support could do it. You either have to take the drive to a data recovery company (Very expensive for a locked drive) or format it. We ended up tracking down the employee and got the password from them. Was nice of him being that we layed him off.|
If you have the password and just want to turn off the Drive Lock then...
1) turn on the machine and press "F2" to go into set up.
2) Press alt-p seven times to go to the last page.
3)Press the down arrow to highlight HDD password. Set a password as instructed and reboot the machine.
4) You can remove this password later once your machine starts fine.
