I'm running RAID 5 using the onboard AMD RAID controller. Until this afternoon I have successfully been running windows, but after a system freeze and reboot, Windows went to system repair. Diskpart reported no drives attached to the system.
Rebooting into the RAID utility, I can see the raid array and it is reported as "Functional".
Rebooting Windows 7 installation asks for a missing driver disk and it also does not display the raid drive
