Software RAID1+0 "disappearance" following 10.5.1 update [scary!]

    Macbook Pro Mac OS X (10.5.1) Sil3132 + QBOX-P + (4) WD 750gig

    I have 5 physical drives plugged into Sil3132 esata card, newly purchased drives in a four bay external enclosure and one smaller drive plugged into a 2nd esata slot (same card) in its own bay. The four drives are RAID1+0 in software. I created this raid array in Leopard 10.5.0 and only days ago (I just upgraded to a RAID1+0 (with all new drives) from a software RAID1 (which functioned in both 10.4 and 10.5) with smaller drives for over a year).

    Getting to the point, I upgraded to 10.5.1 today at work, come home plugged in, everything fine for 30 min. Suddenly doing nothing intensive I got the unexpected ejected disk pop-up for all four drives in the RAID1+0 array. I open Disk Utility and all four drives appear but not in an array, but separate and 'unformatted'. My 5th drive, in its own enclosure, is functioning fine.

    I am kinda of paralyzed with fear right now what to do to save my data.
