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 isn’t able to detect the second one after Windows 10 upgrade.

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

First, you should open your computer again 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. In case you want to view or modify the files stored on the drive, simply press Windows + E and locate the hard drive here, provided that it’s connected to the PC.

To make changes to it, create partitions, or format the drive, you can always 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 if you wish 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, then 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.

As far as the internal hard drive is concerned, 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.

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.

One cutting-edge solution is DriverFix, which will scan your Windows PC and warn you of any device drivers that are outdated, damaged, or missing.

DriverFix updates are released regularly to fix errors, enhance communication, and provide new features and stability to the PC.
