Intel Raid reporting an error

[jhh979s]

I sat down at my wife's computer today and moved the mouse to wake up the monitors. The monitors woke up but I was greeted with a blank black screen. I reset the computer and noticed when it showed the Intel Storage Raid screen one of the drives that is part of the Raid 0 array said in red text "Error". The computer sat at that screen longer than usual but then it booted Windows just fine.
The Raid 0 Array consists of 2 Seagate 7200.10 160GB HDDs. There are 2 partitions on this array. One 40GB part for OS and the rest is for data/apps. There is also a third 320GB HDD in this system for backing up data from the array. I've tested both HDDs with Check Disk and Seatools, long and short tests, but neither HDD showed any errors.
I have already backed up the data on the array, what should I do now?

System is Windows 7 64bit, Asus P5B-E (ICH8R) mobo, C2D E6240, X1900GT, 500W Antec PSU

The intel utility usually has some diagnostics in it. Run those and see if its just something with the array config or if its thinking something is wrong with the drives.

I ran the intel raid verification test. It did not find anything wrong. Is it safe to assume it was just a fluke?

If you're really concerned about it you could get a program like spinrite and run the maintenance scan on it to check for bad sectors.

Also, how is that set up? Is it like a raid 0+1 with automatic mirroring of the 2 160's to the 320GB or do you do manual back-ups? I was under the impression that the drives generally had to be identical to do mirroring.

It would work in a 0+1 (160+160=320), but i just back up manually. I'm not too worried about it, seems to be working fine. For now I've marked the drive as normal and it has not given the error again.
