I got my 5g this week. but i'm not able to do a couple of things. this is my first exposure to ipods. so please be gentle on me. I want to store all my music in the form of folders. but i dont know how to make new folders in my ipod. currently all my music is in the form of a long list in aphabetical order. secondly, i downloaded about 4gb of music last night. but none of it is showing in the ipod. there was some sort of corrupt files iguess. everytime i connect my ipod to the computer, a ballon pops up asking me to run a "chkdsk" in ipod controls. i have no idea of how to do it. can somebody please help me with the steps to follow. i waited for my ipod for a long time. but now that it is here i can hardly do anything on it. somebody please help.
