my 30 gb video ipod does the same thing. i plug it into itunes and it says that ipod is corrupted and if i want to restore it or i can disconnect and connect it again. i restore it everytime and then it says ur ipod is restoring. it says it will appear in the screen after it has restarted. so when it shows up again the same message comes that it's corrupted! i have also tried the 5 r's and i have no idea what to do!!
