    Just noticed that USB drive is seen in Safely Remove Hardware and Eject Media and in Devices and Printers.

    The problem is that when I go to File Explorer ---> This PC I do not see drive.

    Any help would be appreciated.

    Thank you

    Regret I am unable to assist, but noticed your post after I posted mine (WD drives not recongized).
    So it seems the issue not limited to WD . . . Still weird though.
    Everything worked fine in Windows 7.

    Solved problem by going to disk management and assign drive letter to drive to USB drives.

    They didn't show up there either.
    I did another clean install , switched on: nothing
    and again a clean install (yes... indeed 2x)

    After the 2nd oclean install and after turning on the drives, two showed up.

    Rebooted with all drives turned on and now, finally, they all showed up.
    Did this ' safe remove ' thing. All drives correctly removed.

    Kept the drives running. though..

    Rebooted again, just to make sure they would show up again. Nothing.
    Turned off and on again and they showed up.

    Timebeing situation is solved.

    Now trying to find a solution for the next problem: Samsung magicion reporting it is not properly communicating with Samsung SSD. Guess it has something to do with IRST as it does not display my RAID-set.

    My USB3 WD 2TB Passport appeared online as soon as I plugged it it. I'm running WIn10 Build 10240 with all the latest fixes.

    Perhaps the problem is with USB2 drives? I do know that people with 3D printers that use USB2/Serial ports cannot see their printers at all. Seems there is a bug in 10240 having to do with the USB/serial interface. I'm nto sure if this has anything ot do with external disk drives though.
