Unable To Copy Photos From Mac To External Hard Drive

I've had a Seagate 1TB external hdd for a number of years (unfortunately it's the only place with all my data) and it has always worked until a few days ago. Now whenever I try and copy anything from the hard drive, finder will freeze after a few mb have been copied and won't go any further.
I'm using a Macbook Pro Retina and I've installed all the latest updates.
I can still see all the files on the external hdd, I just can't get them off of the hard drive anymore. Can anyone help?
