My OS is XP home edition. I have not downloaded SP1 or SP2 for fear it will cause more problems than it's worth. I have a HP Pavilion 7955 and use the free AVG, Ad Aware, and Zone Alarm. Thus far I have had no problems. I recently installed a 250GB HDD as my "secondary" drive for use primarily to store digital video that I'm downloading for my VHS and 8MM tapes. My OS is on a 40GB HDDD that is nearly full. However, as you may know, I can only access 137GB of this 250GB HDD. I understand the reason....I believe. But, my question is this: Can I use Norton Partition Magic 8.0 to partition this secondary drive to enable me to see the whole 250GB? I am told SP1 would enable me to see the "see" the full 250GB.....but SP1 is not available now as a separate download now (at least I can't find it). It's now a part of SP2 and this must be downloaded in order to get SP1. HP said if I downloaded SP2 several things may quit working.....including the "System Restore" function.
