My Passport is not recognized after clicking noise heard

I have had my WD External Drive (My Passport) for about three years - Absolutely no issues.  Got it to protect ALL of our family photos.  Tonight, tried to open it and I heard a couple of clicking sounds and now the drive cannot be accessed.  Keep getting a message that I must format the drtive to use it.  Does this mean my photos  (and my itunes library) are lost forever?  IF the drive has failed, is there a way to recover the data?  Is it epensive?

Hi there and welcome to the WD community.

I would recommend to contact support before trying anything else:

If you wish, you can use a data recovery software you can do a Google search and check some out since your drive is coming up on the computer.
