I had about 30GB last week and all of a sudden I have 212MB, what's going on, Something has happened but don't know what, I've not downloaded loads of stuff lately, any ideas?
 
Download and use OmniDiskSweeper. It will provide a sorted list of what's consuming your space.

If you run it with sudo (As shown below), it will include some system files that it woud not normally have access to scan. That is a more accurate representation of what's consuming your drive.
Code:
sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper

Another option is to use this terminal command
sudo du -d 1 -x -c -g /

I prefer to redirect it to a text file (this puts it in your Documents folder
sudo du -d 1 -x -c -g / > ~/Documents/du.txt

Like the sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper command, it will scan all directories, but produce a text file as opposed to showing the results in a window
 
thank you. this is the first time I've seen it fall that low, and then the GB available has gone up again tonight by around 10GB, I'm pretty sure in all the years I've owned the MBP I've never seen it fluctuate, but it has today.
