OK, I had a 200GB HDD and was trying to reformat it. The largest I could make the partition was 131GB because my Windows XP CD does not have service pack 1, so it cannot support any drive bigger. I called Dell and told them the situtation. He said just install it on the 131GB parition and after its reformated and SP2 is installed, I can add the rest of the unallocated space to the existing partition. Now how do I add the rest of it to the partition? He said I could do it with a program Windows comes with.
