i looked for the 48bit lba option before and could not find it. i do have xp installed on the 500gb hd and when i looked for the rest of the space on disk management i only see the 137 and nothing else.

when i enabel raid on the motherboard and reboot it tells me to push f10 to do that raid thind but i dont know what to put it on, and every one that i do and try to install xp or reformat, it cant find a hd at all.
