I added a second hard drive to my computer, but it won't format. When I click format in Windows and then try to format, it starts and then instantly says "Unable to complete format." I have Windows XP SP2 with full updates. The drive I'm installing is a Hitachi 200GB. My main drive is an old Maxtor 80GB that I've had for years, but it's starting to get full and I definately could use the extra space. Anyone have any idea why my drive won't format?
