Seagate hard drive light is on but not detected

I. How to solve the problem that the Seagate external hard drive light keeps flashing but cannot be read?

1. Restart the computer equipment

To resolve a failure with your external hard disk device, the simplest solution is to restart your computer.

5. Change the power management settings of the USB root hub

The USB root hub serves as a mediator for data transfer and power supply between the computer and external hard drive. However, the Windows system typically has the USB root hub enabled by default, which can disrupt the connection and data transfer between the two devices. To resolve the issue of the Seagate hard drive constantly flashing without reading, we can disable the option to “allow the computer to turn off this device to save power.”

Step 1: Turn on the computer, find the (Device Manager) application in the search box in the lower left corner and open it. Next expand the (Universal Serial Bus controllers) option.

Step 2: Right click on (Generic USB Hub) and click on the (Properties) option.
