My External Hard Drive Isn’t Detected – What Do I Do?



If your external hard drive isn’t detected, it can be a major hassle. Not being able to access your files can be panic-inducing, but don’t worry – we’re here to help! In this blog post, we’ll walk you through some troubleshooting steps to get your device up and running again.

1. Make Sure It’s Plugged In and Powered On

First things first: make sure your external hard drive is plugged in and powered on. If it’s plugged in but not receiving power, try plugging it into a different outlet or USB port. If that doesn’t work, it’s possible that the power cord is damaged – in which case you’ll need to get a replacement.

If your drive is plugged in and receiving power, but it still isn’t appearing on your computer, there are a few other things you can try. First, check to see if the drive is set to “Safely Remove Hardware” mode – if it is, you’ll need to eject it before unplugging. To do this on Windows, open the “Safely Remove Hardware” icon in the taskbar and select your drive; on Mac, open Finder and click on the eject icon next to the drive’s name.

If your drive still isn’t appearing, it’s possible that there’s an issue with the driver. To troubleshoot this, you can try uninstalling and then reinstalling the driver. On Windows, open Device Manager and find your drive under the “Disk drives” section; right-click on it and select “Uninstall.” Then, unplug the drive and restart your computer; when it starts back up, plug in the drive again and see if it’s now appearing. On Mac, open System Preferences and go to the “Disks” section; find your drive and click on the “Unmount” button. Once that’s done, restart your computer and then plug in the drive again.

2. Try Another USB Port or Another PC

First, try plugging your drive into another USB port. If it still isn’t appearing, try plugging it into another computer. If you’re able to access your files on the other computer, the issue is likely with your original device and not the hard drive itself.

3. Update Your Drivers

One of the first things you should try is updating your drivers. Drivers are the software that allows your computer to communicate with your external hard drive. If they’re out of date, it can cause problems. You can update your drivers manually or, if you’re not comfortable doing that, you can use a driver update tool.

4. Check Your Computer’s BIOS

Another thing to check is your computer’s BIOS. The BIOS is a low-level software that controls your computer’s hardware. Sometimes, the settings in the BIOS can cause problems with external devices. To access your BIOS, you’ll need to restart your computer and press a key (usually F12 or DEL) when it starts up. Once you’re in the BIOS, look for the section on USB devices. Make sure that your external hard drive is set to be recognized as a mass storage device.

5. Enable and Format the Drive in Disk Management

One of the first things you can try is enabling and formatting the drive in Disk Management. To do this, open up your Start Menu and search for “Disk Management.” Once you’re in the Disk Management tool, find your external hard drive in the list of drives. Right-click on it and select “Enable” from the menu. If that doesn’t work, you can also try right-clicking and selecting “Format.” Be warned that formatting will erase all of the data on your hard drive, so make sure you have backups of your important files before proceeding.

6. Clean the Disk and Start From Scratch

One of the first things you can try is cleaning the disk and starting from scratch. If there’s any dirt or debris on the disk, it could be causing problems. To clean your disk, unplug it from your computer and use a soft cloth to wipe away any dirt or fingerprints. Once the disk is clean, plug it back in and see if it’s detected.

If you’ve tried all of these troubleshooting steps and your external hard drive still isn’t detected, there could be a more serious problem. In this case, it’s best to take the device to a professional to see if they can diagnose the issue. With their help, you should be able to get your external hard drive up and running again in no time!
