can raid be set up from an existing install of xp?

[graylinghunter]

I am running my system in normal sata mode can I swap this to raid 0 without a complete re install ?
I have a second sata hd on the sytem? This is used for store at the moment.
one is 300gb and the other 160 although my 300gb has a 160gb partition which has xp home installed.
I have a lot of softwate on this rig and it takes two days to re install.
