Got a nice surprise yesterday--I routinely checked on a new version of Magician--and it told me once again that I was using the latest version of the software...but as I usually do I followed the link to the Samsung site--usually I would expect to see the version number 4.9.7 prominently featured. The day that I made my initial post in this thread the Samsung site was still showing 4.9.7 as the latest version. This time, however, there was no version number listed--and the download was smaller than the 4.9.7 version of the software--so I figured I had nothing lose by downloading it--and Lo and Behold--at long last it was Magician 5.0...! Best part? It's got a new interface *and* it works as it should under the latest builds of Win10x64...! Yes, finally the Magician software properly initializes the driver under WIn10x64, secure-boot On! Better late than never from Samsung! Thought you might like to know! Merry Christmas... AHCI bus and SATA bus now recognized by the Magician software.
