But before moving further, let’s know the reasons behind an undetected Seagate external hard drive. Some common reasons are:

  • Bad USB Port: If the USB port of the computer or laptop isn’t working, it won’t detect your Seagate hard disk. If you are using a USB hub, check if there is a problem with it.
  • Virus Infection: If you aren’t using a good antivirus, your Seagate external hard drive may get infected with viruses or malware. This can also make the hard drive undetected by the computer.
  • Data Corruption: Sudden power outage during data transfer can corrupt the data on the external hard drive and make the device inaccessible.
  • Physical Damage: A hard drive has various delicate internal elements and parts. These parts are sensitive to jerks and physical impacts and can break easily. There is a read/write head that writes data on a magnetic platter. If in case the read/write head or the magnetic platter is damaged, the hard drive won’t work and becomes undetected.

How to Fix an Undetected Seagate External Hard Drive?

Follow the given solutions to fix an undetected Seagate external hard drive.

Solution 1: Use a Different USB Port

Sometimes, due to a faulty USB port, your Seagate external hard drive is not detected by the system. So, try a different USB port for the hard drive. If you are using one at the front of the CPU cabinet, you can switch to the one at the back. You can also try to connect your Seagate external hard drive to another system to check if the issue is with the USB port.

Solution 2: Reinstall the USB Driver

Sometimes, a computer doesn’t recognize an external hard disk because of a corrupt or outdated USB driver. You can uninstall and reinstall the same by following these simple steps:

1. Go to “Search bar” and type “Run” to locate and launch the “Run” app.

2. Type “devmgmt.msc” and click “OK”. It will open the “Device Manager.”

3. Find “Universal Serial Bus Controllers” in the list of devices displayed and click on the arrow icon to expand it further.

4. Right-click the first USB controller and select “Uninstall”.

5. Repeat the steps for all the remaining USB controllers.

6. Restart the computer. The system will reinstall the USB drivers automatically.

Solution 3: Enable “Show Hidden Devices”

If your Seagate external hard drive is “hidden,” it will show undetected on the computer. You can change the hidden device’s settings by following these steps:

1. Go to “Search bar” and enter “Run” to locate and launch the “Run” app.

2. Type “devmgmt.msc” and click “OK”. This will open “Device Manager.”

3. Click “View” on the top and select “Show hidden”.

4. If there are any grey-out entries, right-click and select “Uninstall”.

5. Restart the computer and try to connect the hard drive.

Solution 4: Turn on the USB Root Hub

At times, the external hard drive becomes undetected when multiple devices attached to the same USB hub go into the condition of selective suspend. To resolve this issue, you can try enabling the USB root hub by following these steps:

1. Go to “Search bar” and enter “Run” to locate and launch the “Run” app.

2. Type “devmgmt.msc” and click “OK”. This will open the “Device Manager.”

3. Right-click on “USB Root Hub,” select “properties”, and then “power management.” Uncheck the option that says “Allow the computer to turn off this device to save power”.

4. Repeat the uncheck method for all the remaining USB Root Hubs (if there are any).

5. Restart the computer and see if the issue is resolved.
