MyBook WD3200C032 won't work with Windows 7

im having the same problem, except i went from vista to 7 and now it isnt showing up at all, wheni run the SmartWare utilities and such it says no drive found and when i look at the drive itself the lights indicating how much info is stored on it are not lit up. however it looks as though the “locked” light is on, no i did not have mine pluged in when i installed windows 7, i made sure of it.
