I am running Ubuntu live without any hard drives installed in my pavillion and there is a 3.1 GB file system. It is not on the DVD-r that I put Ubuntu live on. It also appears that someone is manipulating the info and tweaking my live session. How is this possible?

Magic!
More seriously, a few things - firstly that the filesystem on the disk is compressed with squashfs, any changes are temporarily stored in a ramdisk, and lost when you reboot. All this is abstracted away into a single file system through unionfs
The 3.1gb filessytem you see is the unionfs file system, and squashfs makes it possible to fit all that into the livedisk.
Like I said, its magic ;)

thx for the answer but i am still confused. now when i log into live my cd ejects when i click on the wireless icon. My only disk is my cd/dvd it shows 788.7 gb in properties. then there is a little icon when i open my home folder that looks like a hd, properties 3.1 gb. that is some kind of magic to me.– EricApr 8, 2013 at 10:44

Easier explanation: Ubuntu creates a virtual hard-drive in your computer's Random Access Memory. Apr 8, 2013 at 13:11
