1. It’s without a power supply

An external drive receives power and transmits data using the USB cable. They are mostly USB-A and USB-B types.

Each has between six and ten pins that provide the Seagate external hard drive with about a watt of power.

USB gets broken very easily. Due to repeatedly plugging and unplugging of external devices USB ports of laptops get bent out of shape.

Solution – Plug it in on a different laptop

Try to use the Seagate external hard drive on another laptop. If it works, ask a service technician to change the USB port of your laptop.

2. The drivers aren’t working/ are corrupted

Drivers are tiny programs that allow USB and other hardware to interface with Windows. Though Windows 10 and 11 is robust yet at times glitch happens.

  1. Connect your external hard drive to your computer.

  2. Right-click on “Command Prompt,” and select “Run as administrator.”
