Alright, so My ipod is formatted for windows... when formatted in this you can only copy chunks of 4 gig things using it as an external. but if you change the formatt of it to take all sizes, then it's not compatible with mac and pc. =/ i had it originally formatted for pc because i just recently got a mac book pro and it's my primary computer. well on to the hard drive trouble that is related... i'm borrowing my friends external to get a 8 gig file from my pc to my mac. it's formatted in fat32(windows and mac read) but that formatt only allows for a 4 gig max to be put on it at one time... so i guess i'm outta luck there, i've looked at JR split but who knows it that will work. My main q is, i'm going to be getting my own personal external soon and i want to know whats the best way to formatt it that it will mount on my pc and my mac and allow me to copy more that 4 gigs of stuff on it at a time! Please Help.
