    External Hard Drive not showing up

    I have an external hard drive that I have used regularly with a Windows 7 machine via esata
    that does not show up when plugged into my Windows 10 notebook via USB.
    I can see it under the disk management, but there is no drive letter assigned so I cannot access it.

    If there's no letter assigned to it then it's hidden. Right click on it -> Change Drive Letter.... then assign a letter for it.

    I can see the drive in disk management, but the option to select 'change drive letter' is greyed out.Click image for larger version.

    EDIT: I plugged it back up to the windows 7 machine via USB, and it is assigned a drive letter and shows up fine in windows explorer..

    As Oliverpowell said you may first check the option is ticked or not. If still not works, you can try some third-party partition software like AOMEI Partition Assistant or else to change drive letter so that the drive can show up.
