I've tried searching for the anwser to this before but got very confused so here we go again... I'm quickly finidng my iMacs 80 gig hardrive is filling up with my iTunes library. I'm about to convert around 500+ hours of .Mod to .ACC. The iMac is in no way going to handle this but i do have an external maxtor one touch with 160 gig of space and two firwire ports. So can i hook this up and put my iTunes library on this and has it as an external library, and how? Heres the tricky bit, As for the Dell, Could i (if the maxtor was formated to be read by winblows) have the second firwire port up to the pc and have iTunes on the Pc and iMac share this single library?
