3 Ways to Fix Second Hard Drive Not Showing on Windows 10

Most of us probably use only one hard disk drive in the computer, but some people who need more space also tend to use two.

Some users using a second hard drive have reported that their computer can’t detect the second one after Windows 10 upgrade.

Therefore, we came up with some solutions to solve the problem.

First, you should reopen your computer and check if your hard disk is connected correctly. Check out this guide for additional info if you’re unsure what to do.

If everything is connected right, but you’re still facing the issue with detecting your second hard disk drive, try one of the following solutions.

Why is my second hard drive not showing up in File Explorer?

If your second hard drive is not detected in Windows 11 or 11, it’s possible that the second hard drive is unallocated and can’t be accessed.

If your new hard drive is not showing up, it’s possibly not connected correctly or not configured in BIOS, so be sure to check that.

Driver issues or problems with a USB cable or port can cause an external hard drive to not show up on Windows, so ensure everything is connected correctly and working.

How do I access my secondary hard drive?

There are several ways to access the secondary hard drive in Windows. If you want to view or modify the files stored on the drive, press Windows + E and locate the hard drive here, provided it’s connected to the PC.

To make changes to it, create partitions, or format the drive, you can access it via the Disk Management utility that comes pre-installed in Windows.

How can I use two hard drives on one computer?

You can opt for two options to use two hard drives on one computer. You can choose either the external hard drive or the internal one.

If you go ahead with the external hard drive option, all you need to do is plug in the external HDD to your USB or serial port, and that’s it. You are all set to use it, save your files, move files to and fro, etc.

The best part of the external hard drive is that it is movable, and you can detach it and keep it with you, making sharing files more convenient.

Regarding the internal hard drive, you need to open up a few screws on your laptop, find a vacant slot, attach the external HDD to it, and boot your PC to work.

How can I fix the secondary hard drive if it’s not showing up on Windows 10?

1. Check for the driver updates

1. Open the Start menu.
2. Type device manager and open it.
3. Expand Disk drives.
4. Find the second disk drive, right-click on it and select Update driver software.
5. If there are any updates, follow further instructions, and your hard disk drive will be updated.
6. You can also go to Settings.
7. Select Windows Update from the left pane, and check for updates that will allow you to see if overall updates offer something for your hard drive.

If your computer could recognize the second hard disk before the Windows 10 upgrade, there’s a possibility that your current hard disk drivers are not compatible with Windows 10.

However, downloading drivers manually can be a long and tedious process that might affect your PC (if you hit the wrong button). Using specific software to keep drivers up to date is the most efficient method.

One cutting-edge solution is Outbyte Driver Updater, which will scan your Windows PC and warn you of any device drivers that are outdated, damaged, or missing.
