Wouldn't trying to mount an already mounted partition give a different error than the one he is having? I tried this: ~$ mount /dev/sda7 mount: according to mtab, /dev/sda7 is already mounted on /home mount failed

That you are suddenly encountering weird storage-related errors makes me think of a drive corruption or worse (knock on wood) failure. Hope you'll be able retrieve your data.
