Fix: Second Hard Drive Not Detected in Windows 10

Most of us probably use only one hard disk drive in the computer, but some people who need more space, tend to use two, as well. And some of the users who are using the second hard drive have reported that their computer isn’t able to detect the second one, after Windows 10 upgrade. So we came up with a couple of solutions, which, I hope, will solve the problem.

First thing first, you should open your computer once again, and check if your hard disk is properly connected. If you’re not sure what to do, check out this article for additional info. 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.

What to do if Windows 10 Doesn’t Detect the Second Hard Drive

Solution 1 – Change driver letter and path

Maybe your hard disk is properly connected and works well, but if it doesn’t have a letter by its name, you won’t be able to access it from This PC. So, we’re going to change the drive letter and hopefully, the hard disk will show up again. Here’s exactly what you need to do:

Solution 2 – Check for the driver updates

a. Update drivers manually

If your computer was able to 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. To make sure all drivers are compatible, do the following:

1. Go to Search, type device manager and press Enter
2. Expand Disk drives, find the second disk drive, right-click on it and go to Update driver software
3. If there are any updates, follow further instructions and your hard disk driver will be updated

4. You can also go to Settings> Update and check if overall updates offer something for your hard drive.

b. Update drivers automatically (suggested)
If you want to fix this type of issues it’s crucial to keep your drivers up to date, but downloading drivers manually can be long and tedious process that might affect your PC (if you hit the wrong button). Therefore you might want to use this Driver Update software that automatically downloads and installs the necessary drivers. This tool is approved by Microsoft and Norton Antivirus. After several tests, our team concluded that this is the best automatized solution. Below you can find a quick guide how to do it.

1. Download and install TweakBit Driver Updater
2. Once installed, the program will start scanning your PC for outdated drivers automatically. Driver Updater will check your installed driver versions against its cloud database of the latest versions and recommend proper updates. All you need to do is wait for the scan to complete.
3. Upon scan completion, you get a report on all problem drivers found on your PC. Review the list and see if you want to update each driver individually or all at once. To update one driver at a time, click the ‘Update driver’ link next to the driver name. Or simply click the ‘Update all’ button at the bottom to automatically install all recommended updates.
   
   Note: Some drivers need to be installed in multiple steps so you will have to hit the ‘Update’ button several times until all of its components are installed.
