Anyone know how to deal with this problem. Just bought a 200 gb hard drive. It only reads up 137gb with XP build 2600 because of the 48 bit. I only have the 2600 build with out sp1 so it could read the full 200gb. Is there anyway around this outside of buying a new copy of xp. Can I partition it with western Digital software for the 200gb load the old version of xp then upgrade to sp1 afterwards?
