I cant connect an iPod to my PC from a Mac

has anyone ever tried using an ipod on a PC computer after its been formatted to use from a mac? there is software that erases everything and whatnot and returns it to factory setting, and i ran it like i was supposed to. now when i restarted my computer, the ipod isnt being recognized by my computers USB. it says like the usb drive is malfunctioning. i run windows xp and i am under the 2nd windows service update (whatever it is). if anyone had this problem and can figure this it, it’d be much appreciated. thanx
