To hold the operating system files, operating system, save data, all the information in your computer will be saved on the hard drive.

The hard drive keeps all the data even when there is no power. It will stay forever until changed or removed by the computer.

Hard drives use a spinning magnetic disc and magnetically recorded and read from, using a swinging arm with a minute read/write head on it.

Called a hard drive to distinguish it from early magnetic discs, which were made of plastic film and called 'Floppy discs', because they were floppy (but held inside a rigid platic cover.)

Thats why you need to destroy your hard disk drive before disposal of your computer. Make sure the disposal is in a special place for electric stuff.

The data will survive, even when the hard drive is removed. It can be plugged into another computer and read.
