    External hard drive not visible

    Hi all,
    I have a 3TB external hard drive plugged in to my pc. I use it to stream movies and music to a couple of media players in the house via our wifi network. Recently it has disappeared from my view on the pc. When I plug it in via usb, nothing happens, yet when I plug it in to my daughters laptop it is recognised, leading me to believe it is a setting problem with my pc rather than a problem with the hard drive. Can anybody advise how to make it work again.
    Many thanks,

    Hi, is any other external disk recognised? Can you see anything related to it using Disk Management?
    (E.g. Windows key + R, diskmgmt.msc)

    What make is it? Note:
    High Capacity External HDDs Not Recognised in Windows 10 - Forums - CNET

    Try this:

    Have you tried uninstalling everything related to your USB hubs in Device Manager?
    (Windows key + X, control panel, Device manager...)

    Use Device Manager to show Hidden devices and remove the USB drive. Does it work on any other computers? Are you running any kind of third party security software?

    If you are streaming media on your Network, you are best to invest in or build your own NAS.

    Thanks for the replies, I have had a look in device manager, there was a usb device listed as CODE43, I assume this was my external hard drive. I googled code43 and followed the instructions to uninstall it and turn off the computer and unplug for 10 minutes, then start it but that hasn't cured it. When file explorer is open, down the left hand side where it lists the desktop, documents and the hard drives etc, under the network tab is listed my BT home hub and PAUL. If I click on Paul it lists the "G" drive which I cannot see elsewhere but when I double click it a window opens that says "\\PAUL\G (Samsung) is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions. The device is not ready."
    The hard drive is recognised if I plug it in to my daughters laptop. This hard drive has worked flawlessly for six months or so, I download music, films etc and transfer them onto it, it is shared from my pc and we have a media player in the living room and bedroom so we can stream said music, films etc to our tv.

    Sounds as if it may be a permissions issue. Hope someone can advise on that in this scenario. Presumably you expect G: to be the letter assigned to your 3Tb drive..

    Meanwhile, again, could you confirm you can plug some other external disk into your USB ports on your PC and have it recognise ok?

    Yeah, G was the letter for that hard drive when it worked. I have another external hard drive plugged in that works fine, I have plugged the G hard drive into the usb port that the other working hard drive is using but it still isn't recognised. I also think it's a permissions issue but can't work out how to solve it

    Could you post a screenshot of your drive's permissions?

    Rt click drive (it will have to be in the other PC), properties, security, and screenshot of each set of permissions.

    Note I've carefully positioned the slider to show all in the bottom section.
    1 screenshot per group or user name.

    Screenshots: freeware, or the Snipping tool

    Type 'Snip' in the search box.
    Save and then upload using the 3rd icon to the right of the emoticon here.

    It would be interesting to try this on your own PC -
    Windows key + R, enter 'diskmgmt.msc'
    You should see a partition manager window.

    Post a screenshot of what that shows of G, then follow the above on permissions if it will let you.

    You do not have to unplug your computer or completely shut down when making changes on Windows.

    Just reboot the machine. That error usually pops up when the portable device has issues. What is the mfg and model of that portable device?
