Lost partitions!

Anyone with any great ideas on partition recovery? One of my servers went to a hang yesterday, I rebooted and nothing happened.. Both the first and second volumes on the Compaq Array has lost their partition tables, how that now can happen... The first volume contained the root and swap file systems, the second carried the /home sub tree. I've made disk copies with dd to files, but how would I go on from here? gpart doesn't find anything on any of the volumes, I haven't tried Partition Magic yet, someone suggested that one, but I can't see how it would do any good. Suggestions are really welcome! Anders Norrbring Norrbring Consulting
