Commissioned for a hard drive of a laptop hs. It is very compact, a green LED indicates the power / connection and turn red during the phases of activities. Next to the mini USB socket for connection. The case opens with pressure quite easily. It is well recognized by Windows XP. The carrying pouch supplied did a little "cheap" but fulfills its role, to 6.50 Eu is already to have thought. Small, practical, cheap and functional, this is what I wanted.
