Was gifted a laptop running XP. Nice little machine, nothing great but I'll use it, however it seems that whomever cleaned off the old files and data also partitioned the harddrive at 8.66 Gb, the drive is an 80 Gb and shows the "space" not in Drive C as being unallocated. Now I don't want to create another drive but would rather "extend" Drive C to the full volume of the physical drive. Is there anything short of doing a format and full installation of the OS that can be done to allocate the unused space?
