Dynamic Disk Error

I have a Win2000 Advanced Server, RocketRaid 464 with 8 drives in a Raid 5
Array. That array is setup as a simple volume on a Dynamic disk. There are
other Dynamic disks in the system. There is a Basic disk as the boot drive.
I needed to install a different LAN card and to make room I moved the
RocketRaid controller card to a different slot. When I booted up, Windows
"found new hardware" and made me load drivers again. Because of that the
drives in that array weren't reloaded. In fact in Disk Manager there were
two entries, one with the correct size but "missing". One marked as a
foreign disk. When I tried to import the foreign disk it said "INTERNAL
Error - Disk group has no valid configuration copies". It never is able to
complete that step.
The BIOS sees the drive fine. HighPoint's Windows RAID management software
sees the drive fine. But because of some small configuration problem, I
can't import it.
I removed the other dynamic disks, so this is the only dynamic disk
currently in the system. The disk now says Dynamic offline. When I try to
Reavtivate it, it gives me exactly the same error.
I've gone round a few times with the dmpss.exe tool from Microsoft. No
luck. I've done a dmdiag.exe dump of the system and used the info in there
to help change the dumps from dmpss and then restore from that. I think I
may have figured out what to change in those files but now I'm having another
problem. Everytime I make a change to the disk and then reboot, the change
is reverted. I'll make a change, do another dump using dmpss and even dmdiag
and verify that the changes are made. But when I reboot, the changes are
gone. So I can't seem to fix it. I have noticed that when I make the changes
I never see the disk light flash. I even put the drive LED right in front of
my keyboard so I could keep a very close eye on it. Once the system is done
booting, I don't see it flash anymore, even while doing these disk changes.
Where can I find information on the low down details of the configuration
database on dynamic drives? For instance, what needs to be "out of
alignment" for there to be no "valid configuration copies"?
Also, what controls when a disk is going to cache writes and when it
flushes? I have found lot's of information on the subject but nothing on how
to force a disk flush. Why wouldn't a disk write new changes to disk before
shutting down?
