I just got the new 30 GB on Friday. I have Windows XP (SP2) and everything has been installed. I was able to sync with iTunes and transfer songs once so far, but for some reason Windows and iTunes aren't letting me do it again. The last time I connected the iPod, iTunes opened and seemed to be working properly until I started to add songs/playlists to the Library. I noticed ITunes quit recognizing my iPod in the middle of that process, because my iPod just disappeared in the source menu. I checked the iPod tab in preferences and it now always shows "No ipod connected", even when my iPod is securely in the USB port. When I disconnect and then reconnect the iPod, I no longer get the "Do not disconnect" message that I should at first. It doesn't even attempt to autosync and open up iTunes either. Instead, the iPod just automatically goes to the main menu screen as soon as I plug it in. So either the computer (which has no problem recognizing another HP iPod I have) isn't recognizing this one all of a sudden, or this brand new iPod oddly enough isn't responding to being plugged into my computer. I can't even restore it using the updater, because it's not seen by the updater as plugged in either. Any suggestions as far as what to do? Does anyone think this might just be a defective model? Any help would be much appreciated.
