WHAT IS A HARD DISK DRIVE?
Hard disk drive is the main, and usually largest, data storage device in a computer
The operating system, software titles and most other files are stored in the hard disk drive.

HISTORY OF PORTABLE HARD DISC DRIVES.
Before the disk drive there were drums... In 1950 Engineering Research Associates of Minneapolis built the first commercial magnetic drum storage unit for the U.S. Navy, the ERA 110.  It could store one million bits of data and retrieve a word in 5 thousandths of a second..

HOW HARD DISC WORKS?
Nearly every desktop computer and server in use today contains one or more hard-disk drives. Every mainframe and supercomputer is normally connected to hundreds of them. You can even find VCR-type devices and camcorders that use hard disks instead of tape. These billions of hard disks do one thing well -- they store changing digital information in a relatively permanent form. They give computers the ability to remember things when the power goes out.

HOW TO LOCK / UNLOCK THE HARD DISK DRIVE?

unlock x:
The x represents the letter of the hard disk drive that you wish to unlock. For example, if you needed to unlock the C: drive, type c in the place of x.

lock x:
The x represents the letter of the hard disk drive that you wish to lock. For example, if you needed to lock the C: drive, type c in the place of x

CAPACITY AND PERFORMANCE
A typical desktop machine will have a hard disk with a capacity of between 10 and 40 gigabytes

Data is stored onto the disk in the form of files.
A file is simply a named collection of bytes

STORING THE DATA
Data is stored on the surface of a platter in sectors and tracks
Tracks are concentric circles, and sectors are pie-shaped wedges on a track

CONCLUSION
To continue the progress and evolution of the HDD over the next 5 to 10 years will require substantial investments in research and development to generate the understanding and knowledge of how to extend the existing technologies and how to create the necessary, new technologies
