Thanks folks for the info.
Have installed it and partitioned it using XP.
I've used Norton Ghost to back up everything to one 'partition', while I've created a complete copy of my original drive to the second 'partition'.
I'm not sure if it's totally necessary. However, as well as having all my data backed up, I figured having all the settings etc saved as an image would be useful should the 'worst' occur.
In theory, I can schedule a backup which I think then simply updates the files without starting from scratch each time.
I guess I'll know in the next few days or so!
Cheers
