Troubleshooting: Why Is My External Hard Drive Not Showing Up?

When your external hard drive is not detected, start with some basic troubleshooting steps. These small checks can often save you a lot of time before delving into more complex solutions.

Ensuring USB Ports are Functional

First, let’s ensure that the problem is not with the USB port:

Unplug the external hard drive and connect it to a different USB port. Sometimes ports get faulty.
If you have another device, plug it into the same port. Check if that device works.
Avoid using USB hubs for testing, as they can add another layer of complexity.
If the drive lights up but is still not showing, the USB port might be providing power but not transferring data.
