The Toshiba MK1234GSX
The top plate of the Toshiba 120GB MK1234GSX hard drive is adorned with a single label, listing its capacity, model number, serial number and other details. If it wasn't for the label, you wouldn't even know it harbours a capacity of 120GB!
As you can also see on the label, this hard drive was manufactured in Japan, although it probably contains components sourced from other countries.

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 drive bay.
Here are the other views of the Toshiba MK1234GSX hard drive. As you can see, it looks just like any other 2.5" hard drives.

We then removed the PCB. This what the hard drive looks like without the PCB. A black, paper-like sheet separates the PCB from the drive's underside. You can also see the contact points for the PCB (see below).
