Over the weekend, my 1TB HD seemed to fill up to 100%. I tried troubleshooting, and after deleting some music and movies, it is still pretty full, more that what I would expect it to be.
Attached is a screenshot of my Disk Usage Analyzer, and below is what I get when I run df-h. My Public folder is only ~280GB, so I don't see what else is taking up so much space.
