I have a Sansa Fuze MP3 player, it's 4 GB.
I plug it in my Mac I have a capacity of 3,7 GB of which apparently 1,8 GB is in use.
Problem is I only have arround 120 MB of MP3s on it...
Who's stealing my free space ?
Here are DiskInventoryX screenshots. I have the same results with du and the terminal.
