Hello, First off, i must just say, i'm new to the Mac world, having used Windows for most of my life! Anyway, the problem i'm having is that in finder, the "Available" disc space at the bottom of the screen is wrong, well, i'm sure it is. Currently showing 254mb AVAILABLE!, well, it fluctuates between about 600 and 200, but, i've got the 1.25ghz Mac Mini, 256mb RAM and 40gb HDD, i've got a 160gb external HDD with all of my files on, on the Macintosh HD there's only a few word documents, a few apps, and Mac OS X 10.4 (Tiger), well, that's all that i can see when i've been through every folder, twice, checking for the large sum that's gone AWOL! I've tried the following: Repair Disc Permissions Reset PRAM and also, my friend (an experienced Mac User) SSH'd into my Machine to try some things but also couldn't work it out. Do you have any ideas? Thanks.
