Western digital hard drive essential edition

Hello,

i have a western digital essential edition whcih i have had for few weeks it is a usb plug and work connection

it has worked ok up until yesterday when it lights up and the two blue light are shown as solid lights on the hard drive

it says on the device manager it is connected and working however it is not shown on my computer when it recognised it previously it was shown as f drive

is there anyway of resolving this issue or is the hard drive faulty ?
