I'm trying to move to a bigger disk in a Small Business Server 2003. Currently, it has a pair of mirrored, dynamic disks that hold two partitions, C and E. The C partition has become too small. I've put in new bigger disk. Because the C-Disk is on a dynamic disk, I had to backup to a different disk and restore it to the new disk, increasing the size. I'm concerned about rebooting this way, though. When I took my mirrored set offline (unplugged the power to them), and restarted with just the new disk, it doesn't boot up. If I leave my old mirrored disks in place, I'm worried that if I boot up and choose the new disk, I may not be able to get back to my old set. What do I do to make sure that I can reset the partition on the original, dynamic mirrored set in case I have to "go back?"
