Thanks for your suggestion - I re-jinked the harddrive to ext3 and 
everything is fine now. I couldn't get Fedora to re-do it though it kept on 
complaining when writing the fdisk changes so I eventually lost patience and 
used ubuntu on another machine to nuke the drive and get ext3 on it.

It's working exactly as planned now.

Thank you.
