I'm having a problem with my 30GB 5G ipod. Every time I connect it to my MacBook running Leopard it tells me that I need to restart my computer. This is an ipod that I've been using for quite a while and I've never had this problem before (it just started happening within the last day). I should also mention that I have a 2G Touch and an iphone 3G and I'm not having this problem with either one of those devices. Any idea what could be causing this and how I can fix it?
