Thanks everyone!

@Luke Hankins: Thank you for the wish of good luck.

@Steven Kurylo: The new RAID set was for user data, to replace a single hard
drive environment. Completely independant from the OS mirror set, and not
using the same RAID controller.

@Daniel Pittman: Yes, I believe you are correct - Silicon Image and I
definitely think that it is of the lower quality kind. Apparently I did have
too much confidence in the RAID array telling me when something was wrong. I
believe that you might be correct that a disk dropped out for a while, but I
have no good way of verification without pulling the drives and testing them
one at a time. Which I'm not sure what will happen when I put both of them
back together in the RAID set - I don't think it gives me any options to set
a master.

@Edward Ned Harvey: Small Business Server has an updated ntbackup that will
backup your Exchange data - it's worked in the past and I have a backup
file, it just won't restore the data for some reason.

All - Thank you so much for your comments and suggestions. I appreciate it
greatly. At this point I think I might need to tell my customer that the
data is most likely gone. I really feel that there was a problem with the
RAID controller - a mirrored set should always be identical unless the
controller encountered a problem. I think the only thing that would have
prevented this is if we performed a full server backup before I began the
work - it just didn't seem necessary to unplug and plug in some hard drives.

Monday is going to be a fun call...

Thanks,
Richard
