A little while back, I thought I lost my Mini. Power supply or something quit. Saved the HD, placed it in a dock, and all was good. Connected it to my Chromebook, and it mounted, everything was still there. Fast forward to today, finally got around to hooking it up to my brand new Mini that I got last week, and lo and behold, it will not mount. Tried all of the USB ports on the back, nothing. Tried the USB port on the keyboard, nothing. Hooked up 5 different jump drives on all the USB ports, and they all mount. OK, weird. Hook the dock up to the Chromebook again, and it mounts. What in the heck am I doing, or not doing??????
