Very good product. No worries then formatting of non-recognition as explained in another post. The lid is removed with the 4 screws (no tools). However, setting the hard drive is done with 4 small screws (supplied). Handy switch will turn on the disk when used. It is true that the cables supplied are really short (eSATA and USB)! I could install a 3TB drive in Windows 7 without problems.
