With the help of Mr Google, I seem to have fixed it. At first it reverted to Japanese and lost everything, then I found how to get English, then eventually ran a disc check and in the end it appeared as a new I Pod. Put all stuff back on. Working well. I use it up and downstairs on I pod / DAB FM radios instead of a CD Player. Cant understand why Apple stopped making them - 120 Gig is great for music storage, and I don't want to keep the phone hooked up to the player. Could use Bluetooth to PC I suppose , but the Classic is what I want .My phone only has 16 Gig anyway.
