Missing / blank hard drive space

[bisento]

Hi

I have recently been having hard drive space issues. I have OS X 10.9.2. Attached are stats from About This Mac and Terminal. I have two queries:

1. What is the unlabelled 392 gb from the Terminal?

2. In About This Mac, the Audio size seems very high. My music folder is about 175gb. I understand that 'Audio' encompasses more than that, but this seems very high. I don't have much in the way of games etc. The same can be said to a lesser extent of movies and photos. By adding up all of the key folders, I get to a much lower usage than About This Mac suggests.

Thanks

That's your root directory and its a sum total of all your space

I recommend that you download and use OmniDiskSweeper. It will provide a sorted list of what's consuming your space.

Run this command in Terminal and post up the output.

sudo du -d 1 -x -c -g /

Aha, I think I have figured out what happened - might be useful information for others.

Something went wrong when I updated to Mavericks last year and my computer got wiped. I just reloaded lost material from external backup and didn't really worry any further about it. But - it seems that in fact those 'lost' files remained on the hard drive, so my user profile was effectively duplicated (thanks also to my own acts), but one has remained hidden. So close to half of what's on the hard drive is unused files / duplication.

Thanks to both replies above from maflynn and Weaselboy - helped me get there.
