External Hard Drive Not Showing Up or Recognized? Here is how to fix it!
Fix External Hard Drive Not Showing Up or Recognized: External hard drives are very useful when you want to increase storage space. They enable you to store data at a place other than your computer’s primary storage and that too at a relatively lower cost. They are easy to use. But, sometimes it may occur that even after connecting your external hard drive to your computer, it doesn’t show up or get recognized. There can be various reasons for your external hard drive not showing up like dead USB ports or driver issues. If your computer fails to detect your external hard drive, here’s what you need to do.
Before you move on to the following methods, you must first ensure that your drive’s power switch is on (if it exists). The lights on the device will indicate that. While most of the external drives are powered over USB itself, some may have a separate power cable. In such a case, you must ensure that the power cable is working fine. If it isn’t working, the power cable or your power outlet may be damaged. If you have checked all of this and your drive doesn’t show up, continue following the given steps.

Make sure to create a restore point just in case something goes wrong.
Method 1 – Try Using a Different USB Port Or Computer
Try inserting your hard drive in some other USB port to check if there’s an issue with the USB port itself. If your external hard drive shows up on inserting it in another USB port, then your previous USB port may be dead.
Also, try inserting your hard drive on some other computer. If it doesn’t show up on the other computer as well, there may be a problem with the hard drive. It may even be completely dead and you might need to replace it. This way you will know where exactly the problem lies.

9.Finally, select the latest driver from the list and click Next.
10.Let the above process finish and restart your PC to save changes.
Method 5 – Create Partitions for your External Drive
If you are connecting your hard drive for the first time, then it is possible that it does not show up because it doesn’t have any partitions. For a previously used hard drive too, partition issues may cause it to not be detected. To partition your drive,
