Trouble with RAID... 'Offline members'... :-/

Hi all!

I have aShuttle SB81P barebone (chipset: Intel 915G + ICH6R. Contains
2x 300 MB S-ATA drive, configured partly RAID 0, partly RAID 1 with
Matrix RAID [ http://en.wikipedia.org/wiki/RAID#Matrix_RAID ]).

After putting the barebone back together when it returned from RMA
(where they replaced the PSU) it booted fine the first time, with the
whole mixed RAID 0/RAID1 array functioning fine. However, after a
reboot I got a message before windows boot that there are no RAID
volumes present, and both drives are listed as 'Offline Member'. How do
I get my RAID 0/RAID1 working again, without losing data?


Regards,
Evert
