Customer has a Perc 6i RAID controller with a 4 disk RAID5 setup with a SBS 2008 One disk failed but due to corrupt to a few corrupt files and backups failing because of the unreadable corrupt files the backups were failing. The failed drive wasn't replaced and server was running with degraded RAID5 until data could be moved to a new system. Apparently there was still critical data  on the server but now the RAID fails to boot. CTRL R to enter the Perc setup utility shows one disk shows as Online but greyed out 2 disks show as Online and one disk shows as rebuilding. Is there any way of rescuing this?
