i have a quick question regarding my new 4G 20GB ipod. first, a bit of background information - i was planning on buying an ibook this summer for my next semester at school, and when i saw the cram and jam rebate, i decided that the discount was too good to pass up. so i selected the ship seperately option, and of course, my ipod came days before my ibook. since i was anxious to get my ipod off the ground, i first formatted it on my older pc. there were no problems a few days later integrating it to my ibook, but when the latest ipod update was downloaded, i was forced to restore the settings because of the windows formatting. a bit of a hassle re-ripping my albums, but overall no big deal. however, after this incident, i noticed on itunes that the capacity didn't add up to 20 GB. sure enough, i power on my ipod, and go settings>about> and this is what it reads - my name number of songs capacity 18.5GB version 3.0.1 sorry for my first post to be a lame help post, but does anyone know whats happening here? should i try another reset to factory settings?
