I was having this problem just now but i figured out why.
I was trying to drag a file into another file on my toshiba external hard drive. When i tried this it said there was not enough space to COPY it. Which is why i ended up here. I had to select the hard drive and go into "get info" and add myself to the permissions to ''read and write". BAM!!! problem solved. I drug the file right in with out coping it on the next try.
