I have a new ipod touch 3g 3.1.2 32gb and it is almost filled up, and every time I sync to iTunes (ver. 9) it takes forever to backup!? I have over 450GB of free space on my external hard drive, can I change it so this is the drive to backup onto? My main c:\ drive which Itunes is installed on only has 15Gb free space. For example the last backup took 1 hour 15 minutes!?!
