How to Fix External Hard Drive Not Showing Up

Method 1: Turn to Another USB Port or Computer

If you find your external hard drive not recognized by the computer, the problem may occur in the port that is used to connect your device to the computer. In this case, you can unplug it and try another port to see whether it works or not. When it works, we can be sure that the former port is dead.

If you are using a USB hub, try to connect your external hard drive to your computer directly, because some USB hubs cannot provide enough power for an external hard drive to function.

What to do if it still doesn’t work after all these steps? At this time, it is required to check where the problem happens, your computer or the external hard drive. You can plug the external hard drive into another computer if there is one nearby. Or you can move to the Mac system in case the file system of the external hard drive doesn’t fit the Windows system.
