USB 3.0 External Hard Drive not recognized in Windows 10/8.1

Many Windows 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 the 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.

If all fails, try doing the following!
