I have had bad expiriences with the old motherboard switch - i like to keep a clean house. so i tend to reformat every two months. i just keep all the non system data on separate HD's.

The first time i try'd the switch it didnt really work well... lets just say i will never do it again lol

XP Corp does indeed have the capability to hotswap as it where fixed parts of the hardware with out the system buggin out, but still... i recomend the old format way.

Cheers mates
