My G4 DP 1Ghz tower is running system 10.2.8, installed on an IBM 42.94GB ATA drive. When I "get info" it says 32.94GB are used, and 10GB available. But all the visible directories inside the disk appear to only contain 16.6GB in total. There's a whole other 16 GB missing somewhere, perhaps a large invisible file of some kind. Have run Techtool 4 and Disk First Aid over the disk and repaired permissions etc but the disk is always pronounced OK. Anybody got any ideas where to find and reclaim the missing space ?
