The hard drive isn't show in File Explorer? Here's what you need to do.

If the secondary hard drive isn't showing up in File Explorer, you can use these steps to resolve the issue on Windows 10.

When connecting a mechanical hard drive (HDD), solid-state drive (SSD), or an external USB hard drive to a computer, Windows 10 can usually detect and set it up automatically. However, sometimes, a newly added drive may not show up in File Explorer, which could indicate a number of problems.

For instance, it could mean that there is a physical problem with the data or power connection. If the hard drive does not appear in File Explorer, this could indicate that the device is disabled, offline, or does not have a drive letter. You may be trying to connect a drive previously installed on another computer, the partition on the USB drive may be corrupted, or you could be dealing with a raw drive that was never configured. Therefore it was never initialized or formatted.

Whatever the reason it might be, Windows 10 includes multiple ways to fix the issue and regain access to the drive using Device Manager, Disk Management, and command-line tools like diskpart.

In this Windows 10 guide, we will walk you through several ways to troubleshoot a hard drive that refuses to show up in File Explorer.

How to fix missing hard drive in File Explorer using physical troubleshooting

On Windows 10, if a traditional mechanical hard drive (HDD) or solid-state drive (SSD) does not appear in File Explorer, there are many reasons why this is happening, but before checking and modifying the system settings, try these troubleshooting steps:

• Confirm the hard drive is correctly connected to the computer and receiving power.
• If it is an external USB hard drive, disconnect it and try a different USB port. If you are using a USB hub, try to connect the drive directly to the computer.
• If it is an internal hard drive, make sure the data and power cables are correctly connected to the storage device, motherboard, and power supply. When checking the internal components, make sure to power off and unplug the computer before beginning the process.
• Connect the drive to another computer to determine the problem is not the device.
• Access the computer Basic Input Output System (BIOS) or Unified Extensible Firmware Interface (UEFI), and make sure the firmware is detecting the storage. Since the motherboard firmware is different per-manufacturer and even per-device model, make sure to check the manufacturer support website for more specific instructions.

Once you determine that it is not a physical problem, then you can use the following recommendations to fix the most common problem prevent File Explorer from showing a hard drive.

How to fix missing hard drive in File Explorer using Device Manager

How to fix missing hard drive in File Explorer using Disk Management

There are a few requirements for a hard drive to be available in File Explorer. The device must be online and initialized. It needs to have a partition properly configured. And it has to have a drive letter assigned, or it should be mounted as a folder.

If you are dealing with any of these problems, the steps below will help you to troubleshoot and fix the most common issues with Disk Management.

Set drive online

To bring a hard drive online, use these steps:

1. Open Start.
2. Search for Disk Management and click the top result to open the app.

3. Right-click the disk with the "Offline label" and select the Online option.

   

After you complete the steps, if the hard drive was offline and previously configured, it should appear in File Explorer. If the drive was offline but never configured, continue with the steps below.

Once you complete the steps, this action will erase everything on the drive and prepare it to be formatted if the storage was never initialized.

Import foreign drive

If the drive you are trying to access was configured as a dynamic disk on another computer, it will appear as a foreign drive on a different device, and you will need to import it using the Disk Management tool. This process should grant you access to the data without destroying it, but it's still recommended to create a backup of the data before proceeding.

To import a hard drive with a dynamic configuration to make it accessible through File Explorer, use these steps:

Once you complete the steps, the hard drive will be imported, and the data will be accessible from File Explorer or any other application.

Configure drive letter

On Windows 10, when the hard drive is online and initialized and does not appear in the system, there could be two reasons. The drive does not have a drive letter. Or if it was connected to another computer, and the new system is now trying to assign the same drive letter already assigned to another drive on the machine.

7. Click the OK button.

After you complete the steps, the hard drive data should now be accessible using File Explorer.

Configure new partition

If the drive is online and initialized, you may be dealing with a drive without a formatted partition. In this case, you can use the Disk Management wizard to configure and assign a letter to partition.

To set up and format a hard drive to allow it to appear in File Explorer, use these steps:

1. Open Start.
2. Search for Disk Management and click the top result to open the app.

3. Right-click the partition on the hard drive without a drive letter and select the New Simple Volume option.

   

   Quick tip: Usually, the "basic" drive will have a blue stripe indicating the beginning and end of the partition. Also, make sure to select the correct storage, as the following steps will erase everything on the hard drive you will choose.

4. Click the Next button.

5. Click the Next button to use all the available space for the partition. Otherwise, specify the size in the Simple volume size in MB option.

14. Click the Next button.
15. Click the Finish button.

Once you complete the steps, the hard drive will be listed on the "This PC" page of File Explorer, and you can start saving files in it.
