im on a PC and mine did some wacky ass crap..it just said do not disconnect for a long time..crashed itunes a bunch of times and other crap..then asked for me to restart windows i did...and then i got a nice msg that i couldnt run windows cuz a .dll file was destroyed or some crap...needed to use my windows cd to fix it..and now its half ok...everytime i plug in my ipod my computer freezes up for a bit.. Itunes crashes once or twice and im ready to go!! MY computer is top of the line, though im SP1 so that might be a the problem?
