Some laptops provide a utility to lock a hard disk with a password. These passwords are not the same as BIOS passwords. Moving a locked hard disk to another machine will not unlock it, since the hard disk password is stored in the hard disk firmware and moves with the hard disk. Also, adding a new (unlocked) hard disk to a locked machine may cause the new hard disk to become locked. Also, note that hard disk lock passwords cannot be removed by reformatting the disk, fdisk or any other software procedure. Usually, the BIOS password and hard disk lock passwords are the same and we can recover the BIOS password directly from the laptop security chip (after it is removed from the system board.) However, it is possible that the BIOS password and hard disk lock passwords may be different. In this case the BIOS password will not unlock the hard disk. You can test to determine if your hard disk is locked by attempting to access it in another laptop.
