My RAID appears screwed

[jmc41]

So I booted this morning and got some breakfast, came back and found my computer saying one of my two raid1 drives was screwed. Odd given I put them in about 3-4 months ago.

Rebooted and checked the status and it said degraded, came back into windows which took about 5 minutes of waiting (gave up the first time but just waited the 2nd) - after ages to boot down too and now I have two 320gb drives which aren't raided any more.

Is there any way I can get the raid back without a format? And test the drives to see if one is really dieing already.

[Edit] I actually have two new HDs, both of them are showing as partitioned.
