The first thing to do if your external hard drive is not recognized by your computer is to check if it is correctly connected to your PC. A bad connection or a defective cable can sometimes cause this type of inconvenience. Whether it is an internal hard drive connected to your computer or an external hard drive powered by USB, remember to check that the cables are correctly connected and that the cable does not move on either side. In general, external hard drives come with USB-3 cables in order to offer a high-speed reading.

To verify that the external hard drive cable is properly connected:

  • Make sure the cable is correctly connected on the hard drive side and on the USB port side.
  • Check if the LED on the external hard drive is ON.
  • Check if you can hear the sound of the external hard drive spinning.

If your hard drive passes these three tests, it means that it is properly connected and powered by your computer.

Change USB Port

If your external hard drive is not showing up, make sure that the USB ports on your PC are working properly. It often happens that a USB port stops working properly. Check that the USB port is not the cause of your problem by plugging your external hard drive into another USB port. A PC or laptop usually has three or more USB ports, so try them one by one to make sure they work. Make sure your external hard drive turns on and starts spinning when you plug it into the USB port. If it doesn’t, this could mean that the port is faulty. Switch USB ports until you find one that works. Your external hard drive should show up in Windows once you’ve plugged it into a properly functioning USB port.

Tip: Connect another device to your USB port such as a mouse or a USB flash drive and make sure it is showing up in Windows to ensure that the USB port is working properly.

Manually assign a letter to the external hard drive

If your external hard drive is not showing up even though it is properly connected to your PC, it may be because Windows hasn’t assigned a letter to it.

All disks in your computer have a separate letter assigned to them by Windows, your internal hard disk for example usually has the letter C and can be divided into several partitions, each with a different letter.

When you plug in a USB stick or an external hard drive, Windows will automatically assign a letter to it (F: or G: for example), but sometimes Windows does not assign a letter to the newly connected hard drive, if this is the case, it will not be displayed on your PC. In this case, you have to manually assign a letter to your external hard drive so that it is displayed on Windows. To do this, follow the steps below.

  • Right-click on the Start Menu and open Disk Management
    Open disk management tool
  • Search the list of drives for the external hard drive.

  • Click on “Add new
    Click on Add New
  • Check the “Assign the following drive letter” and select a letter on the right.
    Assign a letter to your external hard drive
  • Click on OK
  • A new drive will show up on the computer with the letter you assigned to it.

Once you have assigned a letter to the drive, open your computer where you will now find that a new external hard drive has shown up carrying the letter you have assigned.

Format the external hard drive
