The last thing I remember was that I was trying to import some templates to DVDSP4, all of which is on an external hdd, and I got the warning that "my startup disk is almost full." According to Finder, I only had a few megs left on my internal hdd from 12 GB some minutes ago. I rebooted and emptied the Trash but I still only have 2.15 GB. What happened to the rest of my hdd?
