i am missing over 50gb worth of unallocated space on my hard drive. in disk manager my 200gb hard drive shows to have 1, 130gb partition(that windowsxp is installed on) and no unallocated space. Disk director, partition magic, and many other partition help software also don't recognize any partitions besides the 130gb. i attempted to zero out my computer to fix teh problem using a killdisk bootdisk. it was able to see the 130gb partition and 60gb unallocated space, and i was also able to zero the entire hard drive into a sinle 200gb unallocated space. Unfortunately, when i put in the windowsxp cd, all the installer could see was 130gb unallocated to load windows onto, i installed windows, and i am exactly back to where i started.
