Submitted by: Murtaza
Hard disks in them contain various components such as Platter, Spindle, Actuator, power connector, Jumper block, IDE connector etc.

★ In the inside of a hard disk there is the spindle which is used to hold circular magnetic disks also known as platters. They are usually made up of a non magnetic material, ( aluminum alloy).
★ These platters are spun at speeds in excess of 4000 RPM, nowadays 7200 RPM based hard disks are common enough.
★ The read and write heads work on these spinning platters to read and write data. They are controlled by an actuator arm that prevents any error.
