My hard drive is showing up as having only 114GB left out of 500.
The data using this up is catogorised as "other" - how do I identify what would be taking this much space, when this is a relatively new machine with not a lot on it?

OS X Lion: About Time Machine's "local snapshots" on portable Macs - http://support.apple.com/kb/HT4878 - “You may notice a difference in available space statistics between Disk Utility, Finder, and Get Info inspectors. This is expected and can be safely ignored. The Finder displays the available space on the disk without accounting for the local snapshots, because local snapshots will surrender their disk space if needed."
