Not exactly sure what happened, but I think it has something to do with the new iPhoto?? I booted it for the 1st time off my external drive to create a X-Mas Card and imported 4 photos into it. Don't know if after opening it, it attempted to import all the photos from my external drive to my internal drive?? Don't know why it would do that but there is no sign of it in the Pictures folder. Any ideas?? Only other thing I did was sync my iPad, so I went into my backups and deleted all those files and it freed up 16gb.....I started last night with 44 gb and don't know where in the f the rest of my space went?? I've used DriveSlim to attempt to find any wasted space, but nothing turned up Is there a way to see specifically what happened last night?? I have Time Machine running I've restarted my comp, and still stuck around 16gbs......clueless as to where this Hard-drive space is being used. I've gone thru all my main folders (pictures, music, movies, etc...) and its not being wasted their....has to be hiding somewhere in my Library or what??
