I'm not exactly sure but it looks like your card got corrupted somehow. At least you still have your important stuff. Try formatting your card and make sure you put the important stuff from sd card to your comp then format it.
If you have downloaded any applications recently and do not scan your phone for viruses, now's a good time.
It's possible that this could be malware... or something else.
Might help you eliminate a few causes off the list.
