Passport Essential SE - opening / copying files taking hours

My drive has become very very slow , first it take 10 ~ 20 minutes to be recognised by my PC ( windows 7) , then although i can see all my files but to open them also takes long time ( 30KB - 10 MINUTES ) , I tried copying all my date to my PC hard disc but looks like only reading the data it will take years and then copying …no idea ,  i also tried to do quick smart but Failed message appeared ,

Unfortunately, it looks like your drive is about to fail, try to backup your data to another location and replace that drive.
