Damn. Yesterday 4G 40gb started displaying the exclamation mark & folder icon after I accidentally and stupidly unplugged it without unmounting it first. Then tried restoring it tonight with iPod Updater but this failed with an 'unexpected error' message and there's an ominous clicking sound coming from it. It's past its warranty. Options? Buy a new one? Get it serviced? That can also be quite pricy. Opening it up and messing with it myself?
