Nothing to say about the hard drive itself, which ultimately does his work (until when ???). By cons VERY bad return on the package from Amazon. A simple cardboard disk size is not at all suitable for the effective protection of a hard drive. The result: a first received disc that does not format, returning defective, a 2nd disc that works for now but who can say how much he suffered during transport and its impact on the life .. . Unlike usual, Amazon is very bad on the packaging should be avoided for this reason.
