My hard disk reports that it's full when there should be about 6GB free, so I'm trying to find the extra 6GB of data so I can delete it. I've used Get Info to check the size of all the visible folders in the root directory, but none of the extra data showed up there. I've also tried rebooting and emptied the cache for my web browser, Safari, but that also did not change anything. What would be causing the disk to fill, and where would I find the extra data?

How do you know there should be about 6 GB free?

There was 6GB free the day before and my backups have 6GB free. It literally happened overnight.

Thanks for the help, I found the problem. The system somehow copied one of my external drives to /Volumes/External-drive instead of mounting it there. It must have occurred during a backup.

I wouldn't have found it if I hadn't tried OmniDiskSweeper. It started calculating the size of my external drives which I didn't want it to do. So I disconnected the drives, started over, and found one of my drives "still connected".
