Oh, so M$ have greyed out RAID 5 on Windows 7, pity, I need it. So, has any clever person manged to enable it? Perhaps use the code from Server 2K8? Diskpart can create RAID 5 arrays, but when you boot up se7en they ain't there? The hack that is used in XP don't work, as the disk manager is different. I know I can get a HW Raid controller and do it that way, Or get a MoBo with a Controller that does RAID 5. But they all cost money, and I already have the OS. Nice little project for some interested Software 'geek'
