Anyone have any clue about the following:
I have a file in /var/mobile/Media called disk. It shows like this:

I can't seem to get a size on this file, and when I try to access its properties via mobilefinder, it just crashes back to springboard. Im wondering if this accounts for my 400mb other shown in itunes. I have a dev team jb 1.1.3. Anyone else see this file/know what it is? Thanks in advance.
