First if this drive came with a power adapter, be sure to use it. Be sure you are using the correct power adapter for the drive as this would cause a problem. Be sure to plug the power adapter into the wall directly
and not through a surge protector or Extension cord as this diminishes the power. Plug the USB cable into the Back
USB port of the computer not the front (desktop) and not through Docking Station (laptop).
With the drive plugged in, go to Start/Run and type devmgmt.msc
and press enter. In the Device Manager, are there any devices with yellow marks or under U
us Controllers is there an Unknown Device
? If so, right click it and choose Uninstall.
Pull the USB cable out form the computer end
and restart the computer. And follow the steps above to plug it in.
A USB powered hub
may work but try the things above first.
