I'm really really sorry if this is an annoying question but I've had a quick search around and can't find the answer to my question.

I left my iPod connected to my PC while it was updating. When I came back, stupidly, I assumed it had finished and disconnected it without checking it had a tick on the front. When I disconnected the tick came up and it said safe to disconnect. Ooops.

The battery level indicator was dead low - I wonder if this is why it hadn't updated?

Now when I connect my iPod to my PC iTunes doesn't start up as usual and when I start it, it doesn't recognise the iPod. I tried 'safely removing hardware' but it doesn't work and so I just disconnected anyway.

Now it says (after the iPod has been removed) 'iPod Not Readable' and that I need to reformat.

Should I reformat?

Thanks in advance...
