    Laptop does not see USB3 external drive


    have an Acer laptop with W8 pre-installed.
    It has an USB3 socket.
    When I plug an external drive into it the drive appears in the device manager but not in "my computer"
    Any help would be great.

    Which Acer laptop model?
    Make/model of your USB3 drive?
    Does your device manager say that the driver is "working"?

    Laptop is Aspire V3 551
    USB3 drive is Intenso 2.5" 500gb
    Device Manager says it is working fine.
    I have updated driver,uninstalled and reinstalled but still no luck.
    I did have some advice from a friend who says the software is seeing the drive but the pc is not.
    Then he mentioned something about changing the legacy in the bios but at that point I am afraid he lost me.

    Is the drive pre-formatted with a file system?

    I am not sure.
    My laptop is the only
    device I have with a Usb3 socket and as it cannot see the drive I do not know how to find out.

    Ah OK. Did you try running the disk management tool? It should see it. Then you can partition/format it from there. If it's not formatted with a known file system, then it won't show up under My Computer because Windows won't be able to mount it.

    I have opened up disk management but am none the wiser.
    It shows disk 0,1, and cd rom
    Cannot see any mention of the usb3 drive.

    If you unplug USB3 drive, does it still show disk 1? Maybe post a screenshot of your disk management screen.
