The Package
The Seagate 120GB Momentus 5400.2 notebook hard disk came in a plastic bag which protects it against electrostatic discharges.
Behind, the sticker sealing the bag warns against handling the drive without anti-static precautions.
Inside the anti-static bag is the focus of this review - the Seagate 120GB Momentus 5400.2 PATA notebook hard disk!
We will examine this drive in detail soon enough, but let's go through its specifications first.
