Plug in the drive before starting the PC (cold booting) and see if it is recognized.
If that dose not work get the latest drivers for your ext hard drive.
If that does not work download the western digital recovery tools and do a complete scan of the drive.
If your drive cannot be recognized there are options, such as mounting it in unix, but this really isn't a job for an amateur - you're more likely to cause more damage.
