Technically its a 160GB SATA HDD in an Omata enclosure.
This is the best quality enclosure i could find at the time, not like those cheap aluminium ones. This has a rubbery type feel to it and is well made. approx 13 x 8 x1.5cm
The drive inside is a Fujitsu 160GB SATA.
It comes with a wallet thingy (pictured), a twin USB lead and a screwdriver if you ever need to swap drives.
Its about 2 months old and ive probably used it twice (hence the sale), i bought it to use with my wii but never got around to it.
MINT conition, Its been in my laptop bag since i had it so theres not a mark on it.
