my old G4 desktop is running 10.4.11. i recently had to do an erase and install due to various reasons. after reloading my iPhoto library i was told that my disk was almost full. i should note that i was expecting to have at least 16 gigs of free space when all was done because that's where i was at before my erase and reinstall procedure. it's an 80 gig factory HD BTW. upon double clicking on my HD, oddly, it says i still have 73 gigs of space left- which makes no sense given the amount of photos and videos that were just reloaded. but then when i click on to my Pictures folder i'm told i've only have 140 MB. what gives?
