I have picked up from all computers that I've ever owned (from Win98SE) each hard disks. Currently I have a brisk DELL and wanted to read data and Old put together. After several wrong orders, all of which did not come to his chair, I have now tried this set. I currently run (yet) Win7 32bit. I unpacked everything, then plugged in and lo and behold, all the plates are detected immediately. - What can not be seen at Amazon, is located the adapter power supply for large plates at. - The turn is a three-wire cable transition piece and a four-wire cable transition piece. - The three-wheeled you can safely throw away, because that does nothing. It is not explained in the description of where it is to serve.
