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.

The hard disk cage

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

To continue disassembling the Hitachi Travelstar, next several small Torx screws must be removed. So, too, must the drive’s label.

Disassembling the Hitachi Travelstar

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.

Inside the Hitachi Travelstar

Once the seven Torx screws are removed, the drive’s front cover (now shown on the left) easily slips away.

Inside the Hitachi Travelstar Hard Disk

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’s a close up of the underside of the Hitachi hard drive’s front cover.

The actuator arm

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.

The Hitachi Travelstar, minus actuator

Here’s the Hitachi Travelstar hard disk with the actuator arm, assembly and circuit board removed. All that remains, essentially, is the Travelstar hard disk platter and the spindle motor hub.

The Hitachi Travelstar platter

The actual Hitachi Travelstar hard disk is smaller than a mini CD. Here you can see it pictured next to a small screwdriver.

The hard disk case

Once the actuator assembly, arm and circuit board, hard disk platter and spindle motor cap are removed, there’s little left behind in the Travelstar.

The spindle cover

The Travelstar’s spindle (and spacer) are tiny. Engineered to perform at precise tolerances, the actual spindle cover and spacer are quite small; they must be to accommodate the smaller mobile two-and-a-half inch hard disks.

The Travelstar circuit board

Removing several additional Torx screws from the drive’s bottom enables slipping the Travelstar’s circuit board away from the hard disk cover.

This specific board features Samsung-manufactured circuits. The board also contains the pin assembly (positioned here on the board’s left edge) used to connect the drive to a PC or IDE cable.

The backside of the Hitachi Travelstar Circuit Board reveals the component was manufactured in Malaysia.

Here you can also see another view of the same pin assembly shown in the last image (positioned here along the board’s right edge).
