Need help about NetRaid 3si

[Sven H÷glund]

My RAID-5-set just splitted in unconfigured parts. In order to get back online with my Netware 5.0 server I need to rebuild my logical set -and here comes the tricky part- without loosing data written on the disks.
I've tried to let the RAID-card examine the disks for information about their former configuration, but it seems as the new, splitted configuration is saved also on them (and I'm pretty surtain that there was no question about saving changes, either).
Is it possible to recover, or can I just forget about it?
