External Hard Drives:

Data recovery services are provided for external hard drives that due to operate due to mechanical, electrical, and firmware failures. Desktop hard drives include hard disk drives, HDD's, 3.5in (inch, 2.5in (inch), and 1.8in (inch) devices. A external hard disk drive is a storage device that stores digitally encoded data on rapidly rotating rigid platters with magnetic surfaces.

Did You Know?

• External hard drives are just desktop or notebook hard drives enclosed in a portable case.
• External hard drives have a x3 higher failure rate than desktop or notebook hard drives.

Mechanical Failures:

What is a mechanical failure? How is it fixed?

All mechanical hard drives operate similar to a record player. Mechanical hard drives are powered by a small 12V or 5V motor which is responsible for turning a spindle. The spindle turns magnetically coated disks (called platters) in a counter-clockwise direction. Heads are attached to an long metal arm (called the actuator arm) which rapidly moves from left to right along the radius of the disk. When operating correctly, the heads are suspended above and below a disk and read or write sectors within tracks on the magnetic surface. Sectors are processed by both the drives electrical and firmware components to produce data. It should be noted that SSD (solid state drives) do not have any mechanical compents and operate using flash based memory).

Electrical Failures:

What is an electrical failure? How is it fixed?

The electrical components of a desktop hard drive are located within the drive chassis and are responsible for amplifying information read by the heads. Electrical components also assist in the mechanical movement of the actuator arm. The replacement or repair of internal electrical components must be performed inside a clean room. External electrical components are located on the printed circuit board and provide power to the the motor, regulate voltage, and interact with the the drives firmware.

Firmware Failures:

What is a firmware failure? How is it fixed?

Firmware instructs the mechanical and electrical components of a hard drive to perform a series of actions. Drive variables such as spindle rotational speed, position of the actuator arm, and the interpretation of data read by the heads is the responsibility of firmware.
