Some Windows 10 users have run into this problem. After connecting an external hard drive to a USB 3 Port, they have found that the computer does not read it. The drive is not recognized by the OS and is no more visible in Windows Explorer. Possibly, the reasons could be due to issues with the USB drivers installed on the computer.
So, in the first place check the type of error message you are getting. Second, run the Hardware and Device Troubleshooter or the Windows USB Troubleshooter and check if it helps. The automated tools check the hardware/USB connected to the computer for any known issues and fix them automatically.
Next, you want to check for any pending updates under Windows Update. Some of the updates might be related to the drivers and therefore needs to be installed on the computer. So check if you need to update your drivers. Visit the related website and search for the latest drivers available for the hard disk model and install it on the computer and check if that resolves the issue.

Next, select Disk Drives from the list of hardware, right-click the USB external hard drive with the issue and click Uninstall.
Following the uninstall, unplug the USB cable. Then, wait for a minute and reconnect the USB cable. The driver should automatically load.
Look for the USB drive in Windows Explorer.

Then, right-click a device and click Uninstall. Repeat the same procedure for all devices.
Once done, restart the computer. Your USB controllers should automatically install.
