I've had my 20GB 4G iPod for nearly two years now, and apart from the clickwheel stuffing up occasionally I haven't had problems with it. Until now. When I went to put some new songs on my iPod just tonight it went haywire and went straight into something like diskmode, with iTunes not recognising it. Then it started to continue to reset, over and over. I then ejected the iPod, and tried to put it back in again. This left my Mac telling me that it could not read the device. So I went into iPod Updater and restored my iPod, successfully. When going into iTunes and trying to load my songs onto it however, my iPod crashes randomly, leaving the blinking "Do not remove" (or whatever it is) no longer blinking, the charging icon was also unmoving. When I ejected it, iTunes crashed, my whole computer started to hang for a minute or two, and then all returned to normal. I'm trying to connect through Firewire on my Mac Mini.
