I'm new here, hello.

I have iTunes 4.11.54 PC, 3G iPod 40gb v2.1 and I'm having problems. I've checked the threads on here and I couldn't find anything dealing specifically with the problem I'm having, so here goes.

I bought a 40gb iPod, yet when it's displayed in iTunes (or Explorer [using Explorer as a mounted drive or Anapod Explorer shell]) it shows 37.1gb total disk space. Now, I'm aware there may be a 1000 to 1024 conversion anomaly, but there's nearly 10% gone on the ol' hard disk. Is this normal or do I have a problem?

There are no other files stored on there, I've even tried updating and restoring to fix this.

Thanks for your help.
