I've used this housing along with a 100GB disc 3 years and was very satisfied until now. In the floor where I work, is designed carpet everywhere. At the end of the day I had the plate "ejected" properly and sought to deduct it. But when I took the case in hand (USB was still connected), there was a violent discharge on one of my fingers. To make it short: The hard drive is over since then, the electronics seems the thousands of volts that can flow in such a discharge, have not survived. The steel case is nice, but since it nunmal is also conductive, it brings me now passed disadvantage. The designer should have but also think of such a case and are installing insulating measures. One can not always take care not to touch the enclosure before the USB connection is not disconnected. I'll definitely be me now have to buy a new plate, along with a plastic housing. Because at least I can be sure that the hard disk is sufficiently protected against static discharges ...
