can this be done? I will have an itunes library on an external hard drive, & possibly 2 ipods, one formatted to fat32 & one formatted to mac os, can I sync my single library to both of them? or can I only have an itunes library on a single ipod at the same time? I would be accessing itunes on my macbook pro 2010 with snowleopard 10.6.3, to sync the ipods. could I do this & keep the fat32 format on one of them?
