Cracking open a laptop hard drive

The Hitachi Travelstar

Laptops are quickly overtaking desktops as the computer of choice. The heart of any

laptop, meanwhile, is its hard drive. Explore this image gallery to see how one of the

world's most popular mobile hard disks (the Hitachi Travelstar) is put together to power

countless laptops. You'll gain a new perspective on the main component powering all

those notebooks you see the next time you frequent the local coffeehouse.

The Hitachi Travelstar mobile hard disk. This model sported a 5400rpm motor, ATA

interface and 40GB of data storage.

Removing the hard drive cage

This particular Hitachi Travelstar was removed from a Dell Inspiron laptop.

Several Philips screws (one of which is shown here at the top left corner) must be

removed to free the Hitachi hard disk from the silver hard disk assembly used to hold the

hard drive securely within the Dell Inspiron's hard disk bay.

This silver cage, perforated to encourage cooling airflow, holds the hard disk securely

within the Dell's hard disk bay.

Once the hard disk cage's screws are removed, the assembly falls free from the Hitachi

hard drive. The Hitachi's circuit board, shown here on the right, is then revealed.

Disassembling the Hitachi Travelstar

5

To continue disassembling the Hitachi Travelstar, next several small Torx screws must be

removed. So, too, must the drive's label.

The hard disk's label must be removed to reveal a seventh hidden Torx screw. Once this

last Torx screw is eliminated, the cover freely opens.

It should be noted, of course, that removing the label (even if the screw behind the label

remains) voids the manufacturer's warranty.

Once the seven Torx screws are removed, the drive's front cover (now shown on the left)

easily slips away.

Removing the cover reveals the actual Hitachi hard disk platter (the large silver mirror-

like disk), actuator arm (whose arm begins at approximately the 7 o'clock position in this

image) and spindle motor (the silver circle in the center). Meanwhile, the actuator arm

mechanism, which is responsible for controlling and moving the actuator arm, is the

silver metallic assembly in the bottom left corner.

Here you can see the Hitachi Travelstar actuator arm, controller assembly and circuit

board. The actual hard disk head, which is responsible for reading and writing data, sits at

the very tip of the actuator arm.

The Travelstar read/write head

In this closeup of the Travelstar's actuator arm, you can see the read/write head that sits at

the arm's tip. The head, of course, is responsible for reading and writing data to the

Travelstar's hard disk platter.
