We setup a new server for a customer and installed Server 2008 on the system. We have a RAID1 setup for the OS, RAID5 for the DATA drives, and a single backup drive we use for Windows Server Backup. After moving the server onsite, 3 hours away, we found out a couple weeks later the power plug on the single drive was loose. We found out because the Backups failed, and after a restart the server would not find the OS. We sent a tech onsite to replace the hard drive, but when we secured the power plug and turned it on it worked like it should again.
So it would appear our MBR installed on the single backup drive, not the RAID1 drives with the OS. How can we move the MBR from a single drive (single point of failure) to the mirrored OS drives?
