Hello, (...) I am very happy with this product. Design exellent, although this external hard drive is dirty, the performance is very good. It is formatted and ready to use (465go). It's not the cheapest HDD market however with Western Digital, one is on quality. I took him a star because it lacks a switch. The drive turns on when the branch and goes to sleep while waiting to be connected to the computer to turn on. In short, this is a good produt that I recommend. I also recommend a cover for transport. Beau robust performance, go there with confidence
