I am trying to reinstall a fresh OS on a RAID striped 0 system. I want to delete and recreate the partition windows is on. However at the XP install screen I only see one drive and it is not the drive my current system is setup on. If I install to that drive it goes in fine but I only see the one drive in windows. If I reboot the machine the system will boot up to the original windows install on the drive I could not see before. It's like the windows install ignores the RAID array seeing only one of the 2 identicle drives and it happens to be the wrong one!
I have files on the second drive I need to keep so I can't delete the array and recreate it. Do I need to install 3rd party raid drivers for windows to see both drives? I did not have to do this with my original install tho. I assumed the default windows drivers would post both drives as it seemed to with the original install.
Thx guys!
