Case 1 – External Hard Drive Not Connected to Computer

Case 1 involves the failure of the computer to read the external hard drive. It happens when you plug in the external hard drive to the USB port.
It is mostly caused by a corrupted external hard drive. However, there are also times when the computer is at fault, and you’ll have to update it for it to work.
Regardless, there are only a few ways to fix this case of the “external hard drive not showing in disk management” error.
1. Uninstall Your External Hard Drive and Reconnect
One of the most commonly used solution by users when facing errors is restarting the cause of the problem. And that’s what you should do first as well.

2. Reinstall Universal Serial Bus Controller
We uninstalled the external hard drive before assuming that the problem is the external hard drive. However, sometimes, that’s not the case.
There are times when the USB port is actually the case of the ”external hard drive not showing in disk management” error. And so this option involves the USB controller.
This is usually caused by a corrupted or unstable USB driver. Just like before, you will have to use the Device Manager to fix the problem. Here are the steps to do it:
- Go to the Device Manager the same way you did before.
- Find and expand the Universal Serial Bus controllers menu.

3. Disable the USB Selective Suspend Feature

So now, we go to the second case of the “external hard drive not showing in disk management” error, which has more solutions.
Case 2 – External Hard Drive Connected But Not Recognized
Even after the external hard drive connects to the computer, it might still not be recognized by your computer.
This is what Case 2 of the “external hard drive not showing in disk management” error is all about.
After a successful connection, a problem will occur again due to many reasons. One of the main ones is due to an outdated or corrupted device driver.

- Go to the Start Menu.
- Click on Control Panel.

If the troubleshooter is able to detect the problem, it’s likely that you won’t have to do anything but wait for the issue to be fixed.
However, of course, it is too easy if that’s the case. So we’ll discuss other options in case this doesn’t work.
2. Update Your Device Driver
If case 1 involves the uninstallation of Disk Drives, then this time we’ll be talking about the update of those disk drive. The process is similar to what we discussed in earlier sections.
- Go to the Device Manager the same way you accessed it before.
- Find and expand the Disk drives
- Right-click on the external hard drive that is the cause of the “external hard drive not showing in disk management” error.
- Instead of Uninstall, select Update Driver Software…
- Follow the instructions that will be shown to you afterward.
If you were able to update the driver software, then there’s a great chance that it will be the end of the “external hard drive not showing in disk management” error, otherwise, you’ll have to proceed to other options.
3. Use Another USB Hub or Computer
Sometimes, you just have to remember that the software isn’t always the problem. There will be times that the problem lies within the USB port. So, to fix the problem, you simply have to choose another USB port and use that instead.
Keep doing this until you find one that works. Now if all USB ports don’t work, you should then proceed to another computer.
However, if that computer still cannot connect your external hard drive, then it might be better to think that the problem lies within your external hard drive.
If that’s the case, we have two more solutions for you that involve altering the drive in order to fix the “external hard drive not showing in disk management” error.
4. Create a New Partition
This time, we’ll be making use of Disk Management instead of the Device Manager. Since we already talked about how to get to the Disk Management in earlier sections, you should already know how to access it.
Now all that’s left to do is the actual steps to create a new simple volume. However, there are conditions that need to be fulfilled before you can do so.
Within the Disk Management window, you should see your Disk numbers such as Disk 0, which is typically the internal hard drive, and Disk 1 which is usually the external hard drive.
If you see the Unallocated attributed on the Disk 1, it should be possible to create new simple volume for the disk.
You just have to right-click on the disk and select New Simple Volume. After that, a set of instructions should show you how to continue through the process.
Regardless, at the end of this, you should be able to fix the “external hard drive not showing in disk management” error. If not, then you should head to our very last option.
External Hard Drives
5. Format Your Drive
