RAID 2+0 Stripe Problem

We had a "flash" power failure and afterwards my RAID array went off line.
It's not a mirrored array, just two 160GB drives connected as a striped array.
I was mainly planning to use this for AV editing, but I also have some other data stored there.
Promise RAID using MBFasttrack133
My operating system is on a separate hard drive so this is still OK.

Initially it just seemed like the array was off line, but after checking for loose connections and rebooting, the second drive reappeared as a new array.

I get the following when I start up:
ID------------MODE----------SIZE----------TRACK-MAPPING------STATUS
1-------------2+0 Stripe----320083M-----38914/255/63--------Off Line
2--*---------1+0 Stripe----160041M-----19457/255/63--------Functional

When I go into the Fastbuild utility I get the following information:

For the first array:

Array No------RAID Mode-------Total Drv------Capacity(MB)-------Status

Array 1--------Stripe-----------------2------------320083--------------Off line


Stripe Block:------64 KB

Channel:ID----------Drive Model--------------------Capacity (MB)
----1:Mas----------WDC WD1600AAJB-00PVA0------160041
-?-:-?----------------failed or disconnected...

Then the second drive in the array now comes up as a second array:


Array No-----RAID Mode------Total Drv------Capacity(MB)----Status

Array 2----------Stripe--------------1-------------160041---------Functional


Stripe Block:-------0.5 KB

Channel : ID----Drive Model---------------------Capacity (MB)
----2:Mas-------WDC WD1600AAJB-00PVA0-----160041


I am thinking of deleting the second array to see if it will return to the fold after a reboot (have serious doubts that this will work).

Anybody know if there is any other way I can try to fix this ?
