Error message - Disk ran out of space unexpectedly. But there's still plenty of space.
I have a 1TB external hard drive that I've been backing up to for several months. It has approximately 715GB available on it. However, I keep getting an error message today that says "The backup disk ran out of space unexpectedly." I did download Final Cut and Motion today and deleted some things from my internal hard drive that I don't use anymore or need.
Any clues as to why I would get this message when the Time Machine preferences states I have more than enough space available?
