• Virus or malware attack corrupting the system.

These are the most common reasons that lead to an unrecognizable hard drive. Fortunately, these issues can be fixed easily.

When you have finished data recovery, you can recreate new partition on the drive to cope with hard drive won't show up issue. Unsupported or RAW file system. If the external hard drive has unsupported files system or hard disk become RAW, the partition bar won't show up in Windows File Explorer. You can only see the drive icon. If your external hard drive isn’t showing up, many things could be causing the issue, including problems with your computer, a hard drive that’s dead on arrival, a fault cable and more.

Part 2: How Do I Get My Computer to Recognize Seagate External Hard Drive?

To help the people dealing with an unrecognizable or undetected Seagate external hard drive, we have gathered the following methods that can be effective to fix the drive.

Method 1: Change a USB port:

In case the Seagate external HDD is not showing up on the system, you need to change the USB port firstly. Make sure that you have plugged the cable in the right way, and there is no fault in the port or cable. Try another port and get a new cable to see if the hard drive is recognized or not.

If you are lucky, then changing USB might be the only solution you need, and the drive will get detected.

Method 2: Check the drive with Disk Management:

Now, moving forward to the techniques that can fix the issue, you need to access Disk Management. The first and foremost thing to do is to check if the Seagate External Hard Drive is showing up in the disk management or not.

Step 1: Open the Disk Management tool by pressing Windows key + X and selecting the option from the list. You can also open disk management by opening the Run dialog and entering 'diskmgmt.msc.'

Step 2: When the Disk Management utility opens up, you will be able to see the drives connected to the system including primary and secondary disks.

Step 3: If the drive is listed in the utility, then create a new volume and assign a drive letter to the external hard drive.

If the Seagate external HDD is still not showing up, then continue following the fixes.

Method 3: Reinstall USB controllers:

One of the most effective ways to fix Seagate external hard drive won't show up on the computer is to reinstall the USB controllers. It means that you have to disable the controllers in the Device Manager and reinstall it. This will allow the controllers to recover the port from the unresponsive condition.

Step 1: Click on Start > Run > Type devmgmt.msc > Hit Enter key and open Device Manager.

Step 2: Expand the Universal Serial Bus Controllers and right-click on the USB, which isn't responding. Select the Uninstall option and remove the USB.

Restart your system and once the hardware changes settle down, reinstall the USB controllers. Hopefully, this time, the computer will recognize the hard drive, and you will be able to access the data stored.

Method 4: Fix the Built-In System Drivers:

There is a possibility that the corrupted drivers or pending update of drivers are interrupting the connection. Seagate external hard drive detected but not showing up might be the result of pending updates. So, update the device drivers as soon as possible.

Step 1: Open Device Manager and select the category of the driver. As we are trying to connect Seagate hard drive to the computer, we will choose the Universal Serial Bus Controller category.

Step 2: Right-click on the driver, and you will see the 'Update Driver' option. Click on it and update the driver. If you don't see an update option inside the Device Manager, you can find the driver on the device manufacturer site.

Updating the driver increases the chances that the problem will get fixed.

Method 5: Remove Virus on the Computer and External Drive:

The last resort will be checking if there is a virus on the hard drive or computer that is leading to this problem. When the Seagate 3TB external hard drive is not recognized due to a virus, that means you'll end up losing the entire drive data.

Generally, an anti-virus and anti-malware program is recommended for the Windows system to prevent such loss. But you can also use the Windows Defender Firewall system to block viruses from infecting your computer and other storage devices as well.

Step 1: Open the Control Panel > Windows Defender Firewall > Turn on the firewall and customize the settings according to requirements.

Step 2: Now go to Settings and select the 'Update & Security' option. This will open the Windows Security system. Select the 'Open Windows Defender Security Center' and choose 'Virus and Threat Protection Settings' from the screen.

Step 3: Turn Real-Time Protection, Cloud-Delivered Protection, and Automatic Sample Submission options.

Once these features are enabled, the Defender will scan all drives and files to detect the virus and remove it immediately.

Why Can't See Files in External Hard Drive & How to Solve

I find files missing from external hard drive become a frequently discussed issue in many forums. So there must be some ideas that catch the point.

Based on this, I decide to make a list of the possible reasons and useful suggestions for users to refer to. Here, I have summarized 4 main causes as well as the solutions in Windows 7 through internet searching and actual operations.

4 Causes That Can Be Fixed Directly in Windows

1. The files are hidden.
2. There are file system errors.

Solution 1:

1. Type cmd to the search box and press Enter.
2. Right click on the exe and select Run as administrator.
3. Input DIR/A x:-s (x refers to the drive letter of your external hard drive). The meaning of this command is: list the non-system files in x: drive.
4. If this command returns nothing, it means your folder has been marked as protected system files, and then you can refer to the second solution.

Solution 2: check whether the files are endowed with system property.

1. Run control folders, or go to Control Panel and Appearance and Personalization.

1. Run cmd.
2. Type the location of the external hard drive. Example: 'd:', 'e:', 'f:', etc.
3. Type dir /ah. You will now see the files/folders with hidden attributes.
4. Type attrib [name of file/folder] -r -a -s -h.
5. You should repeatedly type dir /ah after un-hiding some files/folders so you know if the files/folders are now appearing or hiding.
6. Finally check your external hard drives, all data should be there.

Please note:

• If you're going to unhide files, you should type the whole name plus the expanded-name. Example for file named party: attrib party.jpg -r -a -s -h.
• If you have folder names with 6 characters or more, type the first 6 characters followed by '~1'. Example for folder named birthday: attrib birthd~1 -r -a -s -h.

Possible cause 2 – there are file system errors.

In some cases, the files may be not showing in external hard drive because the file system is corrupted or because it doesn't contain a recognized file system. At this time, you had better recover data from external hard drive firstly.
