WD Hardrive Not lighting up but I hear it humming inside

I just powered up my computer today. I opened some photo workshop programs and tons of files came up missing. I saw my harddrive is no longer lighting up. I unplugged it. Changed power sources. Tried using firewire and mini usb. Nothing. I can hear it humming on the inside but no light shows up on the front and nothing shows up mounted on my computer.

Are you able to try it on another computer?

Yes I tried it on my wifes computer. Tried unplugging it and plugging it back in. Not working still :confused:
