Method 3. Run an antivirus program to solve the “blinking but not detected” error

Your external hard drive may be infected with a virus and therefore the Seagate external hard drive light blinking but not working error has appeared.

Do not hesitate, then, to run an antivirus program and check the disk! Naturally, the antivirus program must be of high quality and also have the latest updates. Only in this way will you be assured of the accuracy of the results.

If this method did not help, proceed to the next one.

Method 4. Check if Seagate external hard drive is a hidden device

The external hard drive can be hidden.

To check that, follow these steps: Right-click Start and select Device Manager. Here click on the "View" tab, and then "Show hidden devices." It is necessary to click the left mouse button on the + icon. Then right-click on the inactive devices and click Delete. Do not forget to restart the computer and you will see immediately whether an external hard disk is detected or not.

But what if the Seagate external hard disk light is still blinking but not being detected? You should refer to the following method.

Method 6. Enable USB Root Hub

Your computer has permission to turn off any external storage to save energy; did you knew that? So, there is a chance that when you turn off this “permission” and do not allow your computer to do that, your external hard drive will work fine.

Use this brief guide:

Open the Device Manager (use Win+X to enter). Deploy Universal Serial Bus Controllers. Select and right-click “USB Root Hub”. From the list, select "Properties" -> "Power Management". Then you will see the text "Allow the computer to turn off this device to save energy." Remove the tick. For best results, these steps need to be done for each root USB hub. Now restart the computer.

It would be a pity if the Seagate external hard disk light is still blinking and not detecting and this method did not help. But do not be discouraged. There are still solutions!

Method 7. Update the external hard disk driver
