Set Hard Drive Password
There is a builtin ultimate security option for computer data in hard disk drives. You may have tried Main-board (BIOS or CMOS) password and windows password protection. I am going to tell you that there is a way you can password protect your hard disk drive.
It is not a very well known fact, but all hard disks have a very strong hardware password capability build in. This password is usually stored both in a chip on the HD controller (the printed circuit board on the hard disk) and on the hard disk itself in a special hidden sector.
For security/protection conscious geeks, it is possible to lock your hard disk with password. A lot of newer laptops will set the HD password together with the BIOS password, completely locking all the hardware for security measures.
