Thanks for that, sounds like exactly what I need but unfortunately that link won't accept my model number and serial combo. I think because mine is a UK drive it has a different product code HD-E2.0TU-UK. Any ideas of how to proceed? I could phone the technical support line but don't know if there's an alternative link / approach?
It works fine with my Mac and never drops unless the Mac goes to sleep which is fair enough - it's only the xbox that confuses it.
Thanks again for the response.
