I have a new powermac with a 250GB hard drive. I had a couple of software crashes the other day (during a Norton AV scan) and now I notice that there is only 48 GB available on the drive! I only have about 40 GB of stuff on it - Apps, Music etc. - and just the other day (before the crash) the available space was closer to 180 GB. So I've got a bunch of space missing and I can't seem to find it! I've emptied the recovery stuff from the Trash, and erased free space with Disk Utility with no result (also shows no problems with a verification check). Yelling nor gentle coaxing didn't seem to help either. Anyone have any suggestions? Thanks.
