hey...thanks for the reply.
but i think i figured out what (most likely) happened. Think I may have clicked on the "wipe all personal data" accidentally, and the computer just took some time to update the "4.15GB free" back to it's current "7.45GB free".
Guess i'll have to reload all my media. Thankfully, I have most of it backed up on my computer. Thanks for the help anyway..
