  1. Large External Hard Drives Not Accessable after reinstall of Windows 10


    I did a full and fresh reinstall Reset this PC of Windows 10 on my Lenovo Thinkpad i7 computer. Now all my large 4tb and bigger external hard drives are not accessable. They were all fine prior to the reinstall.I am able to open smaller external drives without issue. One is via Thunderbolt USB3, the other is USB. Within the Disk Manager, I am able to see the Disk Disk 1, but it is not given a Drive Letter, nor can access the files. I also cannot add a letter. See photos below. Any help with this would be most appreciated.

    :)

    Hi Barbara,

    Hardware failure or corruption within your system files are some of the possible reasons why you are experiencing an issue with accessing your external hard drive. For us to provide an accurate solution, we would need you to answer the following questions:

    • Which build, version and edition of Windows 10?
    • Are you experiencing the same issue when you are trying to access the external hard drive using another PC?
    • What troubleshooting steps have you done so far?

    In the meantime, we suggest running the automated troubleshooter for hardware. Follow these steps to do so:

    • Open the Control Panel.
    • Using the search box at the upper right corner of the window, type troubleshooting.
    • From the search results, click on Troubleshooting.
    • Click on Hardware and Sound and then choose Hardware and Devices.
    • Once done, restart your computer and then check if the same issue persists.

    We are looking forward to your response.

    unrecognised external hard drive on Windows 10

    Since you already reinstalled the drivers of the External Hard Drive, let's run the
    Hardware and Devices troubleshooter as it can resolve your concern. You can do that by following these steps:


    • Press the Start button.

    • Type and select Troubleshooting.

    • Click on View all on the left panel.

    • Select and run the Hardware and Devices troubleshooter.



    If the Hardware and Devices troubleshooter doesn’t resolve your concern, we suggest that you change the letter of the External Hard Drive. You can do that by following these steps:


    • Press the Start button.

    • Type and select Control panel.

    • Select System and Security.

    • Select Administrative Tools, and a new window will appear.

    • Double-click Computer Management, and a new window will appear.

    • Select Disk Management that is located under
      Storage
      in the left pane.

    • Right click on the External Hard Drive that is not showing on the File Explorer.

    • Select Change letter and network path, and a new window will appear.

    • Select Change, and choose the letter that you want for the External Hard Drive.



    After changing the letter of the External Hard Drive, we suggest that you reboot your laptop for the changes to take effect.



    Let us know how it goes.



    Regards.
