I looked around on the net for info on these hard drives and couldnt find any info on what was inside or how to take it appart, so I took the chance, bought one and took it appart to find its what I needed inside...
(sorry for the poor quality of the photos)
So I looked around for a screw hole... nothing under the sticker or feet, you need to carefully insert something between the 2 plastic halves.
I used an ipod opening tool which seemed to work quite well be careful about breaking the plastic locking tabs along the back and side
once the back and side tabs have been losened the hard drive can be pulled up and slides out.
inside is a seagate (obviously) momenus 5400.6 SATA drive (which info I could not find anywhere!)
to reassemble repeat in reverse!
