The Momentus!

Here's a look at the top plate of the 120GB Momentus 5400.2 hard disk. The top plate is adorned with a single label, listing its capacity, model number, serial number and firmware revision.

If it wasn't for the label, you wouldn't even know it harbours a massive capacity of 120GB! As you can also see on the label, this hard disk was manufactured in the US, although it contains components sourced from other countries. The label also includes a short guide for the jumper block.

Except for the PCB, the underside is completely bare. Even the PCB is devoid of any surface-mounted components as this is necessary for the drive to fit within the narrow confines of a notebook hard disk bay.

We then removed the PCB. This what the hard disk looks like without the PCB.

A plastic sheet separates the PCB from the drive's underside. The cut-outs you see are for the three big chips on the PCB. You can also see the contact points for the PCB (see below).

Now, let's take an in-depth look at the drive and its various features and components!
