How to Fix External Hard Drive Not Showing Up (6 Ways)

When you suddenly find an external hard drive that is not recognized by the computer, what can you do to solve this error? In the following content, I'd like to tell you what to do if the external hard drive is not detected, or recognized.

2. 2. Troubleshoot Broken USB Ports
3. 3. Initialize a New External Drive
4. 4. Assign a Driver Letter

6. 6. Update the Driver

Method 1. Open Disk Management to Check the Device

The first thing you need to do is open Disk Management to check the external hard drive.

Step 1. Right-click the start (win logo)

Step 2. Select "Disk Management".

Step 3. Browse the drive list to look for your external disk.

If you see the external hard disk showing up in Disk Management as unallocated/not initialized/offline, it could be easy to fix the external HDD not showing the problem (refer to Method 3). This is what people described as an external hard drive detected but not showing in This PC.

Method 2. Troubleshoot Broken USB Ports

If the external HDD is not showing up when it's connected via a USB 2.0 port, you can also try a USB 3.0 port to detect the drive. Besides, you can try to connect the external hard drive directly to your PC and see whether your computer can detect the external hard drive.

Method 3. Initialize a New External Drive

If your external hard drive is a brand-new disk, you need to initialize it first. Then create a new partition on it. By doing so, you'll make your new external hard drive show up on Windows 10/8/7.

Step 1. Right-click "This PC" (in Windows 10) and choose "Manage".

Step 2. Go to "Disk Management", right-click your new hard disk, and choose "Initialize Disk".

Step 3. Select the disk and choose MBR or GPT as its partition style, click "OK" to start.

Step 4. Right-click on the unallocated space on your new drive and select "New Simple Volume...".

Step 5. Set the volume size, drive letter, and file system as NTFS to the new hard drive.

Step 6. Click "Finish" when the process completes.

Then, you can see the external hard drive show up on This PC.

Method 4. Assign a Driver Letter

Your external could be missing from This PC if it doesn't have a drive letter. Thus, you can fix this error by changing the drive letter.

Step 1. Go to "Disk Management", right-click the disk partition which has no drive letter.

Step 2. Choose "Change Drive Letter and Paths" from the context menu.

Step 3. Click the "Add" button in the pop-up window.

Step 4. Assign a drive letter to the partition and click "OK" to confirm.

Most people could find their external hard drive in Disk Management after assigning a drive letter.

Method 5. Change the File System to Make It Recognizable

Your external hard drive could also disappear from This PC if the file system is not compatible with Windows 10/8/7. Fat32, exFAT, and NTFS have their compatibilities and limitations. If you are using an APFS drive on a Windows 10 computer, your drive doesn't show up. Therefore, you can change the file system to fix the external hard drive not showing an error.

Step 1. Keep the external hard drive connected to the PC.

Step 2. Open Disk Management and right-click the external hard drive with the RAW or unknown file system.

Step 3. Select "Format" and set "NTFS" or "exFAT" for the external hard drive.

Step 4. Select "OK" to finish the formatting.

Method 6. Update the Driver

If the external hard drive works with one computer and fails to be detected by another, you can try to update the external hard drive driver.

Step 1. Right-click "This PC" and choose "Manage".

Step 2. Click "Device Manager" then expand "Universal Serial Bus Controllers".

Step 3. Right-click the device and select "Update driver".

Step 4. Choose "Search automatically for updated driver software" and restart your computer.

When the process completes, you can open Disk Management to check if the external hard drive shows up. If the methods fail to help you, contact the external hard drive seller for refund and exchange services.
