I do have lots of important photos etc. I have nowhere to back it up to so I think I will have to get another hard drive to be able to back up the data first.
I don't really understand though, if I cannot access the drive because it is not mounted, how will I be able to use a disk copying utility to pull the files i.e. how will it have access to the files if I don't? Or is it possible to back up a partition even if it's not mounted?
