Ketron should supply a OS Backup DVD or CD in the package that make it possible to recover the
Audya HD and reset to factory settings.
At least they should have a downloadable iso-file and software to make a total recovery possible.

Regarding HD break down or failure, it's not a question about if it will happen, it's more a
matter about when it will happen......
