Thanks SD - the post there by 'neilslade' looks particularly useful. I was assuming that if I installed the new SATA and made it bootable/partitioned, the potential HAL problem after cloning would be solved, but 'ns' reckons I need to install a new XP on the SATA first? I guess I could just put a bigger IDE in and clone but that seems a retrograde step.
Any readers actually done this?
