Not recognizing mybook

i have a 500GB WD mybook. i plug everything in, i hear the HDD spinning and clicking inside the mybook. the problem is that when i plug the USB cord into my laptop (windows vista) the only thing it recognizes is the: CD Drive (H: ) WD SmartWare and not the usual (i :slight_smile: drive. it doesnt read any of the files i put on it. only the (H: ) drive.  ive had this for a year now with no problems until now. worked fine yesterday and now its not. please help?
