Fairly straightforward query here - I have an old 120gb that came with my mbp, so every gb counts. Formatted size is 111GB, and when I add up all the files on my disk, it comes to ~97GB. However, when I look in the info about the drive, it says I'm using 105GB. I like to think of myself as pretty knowledgeable when it comes to macs (got my first mac in '92), but I can't figure this one out. I do download a lot of stuff frequently and offload it to externals, but I've never had a phantom block of space this large disappear before. Any ideas? Preferably one that didn't involve restarting or running onyx as I don't particularly like quitting applications, but if that's the only solution then I'll take it.
