Move Software Raid Array to new server

I need to access the 3 disk software RAID-5 array from an NT (Alpha) machine that had a power supply failure. I can connect these SCSI drives to an NT(Itel) server. My problem being that I do not have the Disk Administrator backup disk to configure the new server. I do have a backup tape (from several months back). I tried restoring the c:\winnt… folders to a c:\alpha\winnt… folders and used Disk Admin to ‘search for other configs…’ but it found none.
I really would like to get the data from the (now dead) NT/Alpha software Raid-5 array.
