Hi,
First I apologize if i'm not at the right topic or forum for this Raid problem which is maybe not linked with the RST driver.
If you know a better place to ask for advice about such a raid failure I will be glad if you tell me.

- i have a raid 5 with 3 disks, the version of Rapid storage is 11.6.0.1030, on a Z77 chipset Asus motherborad (P8-Z77-v lx). The OS disk is a separated non RAID SSD
- after adding some RAM I had to tweak my bios and change my overcklock params
- as usual this can lead to several reboot, and windows freeze
- i first saw the raid in "VERIFY", then I remember I let windows start with the full verification process (which has maybe broken my raid group?)
- then the raid was FAILED with two disks out of 3 not recognized any more (they are here and living ok, but they are out of the raid 5 group -see picture below-)

I haven't touch those 3 disks since, and I don't know if there is a way to insert back the missing disks in my initial raid 5.. I don't think so. It's maybe juste a header to change..
I'm super sad with the fragility of the raid.. I reboot 5 times and it is completely lost.
As it was partially backed-up with most important things, I think I will not use a low level raid reconstruction tool that take days to determine the raid parity structure get back some files. Even if it maybe would work very well as the 3 disks should have still the full content of the raid (no parity reconstruction needed as when one disk is destructed)

Thanks for your advice if you know a simple solution!

Hi Dieter,
Thanks for your answer.The ROM is 11.0.0.1339
I was not creating the raid array or installing Windows, I just add RAM.. My array contains 3To of datas. You're right I can see that it is risky to overclock a raid config.

I'm ok for a driver update, but I don't see the point in taking the risk to change the driver and maybe not to be compatible with my raid 5 structure. I don't know either what driver is the same branch as mine.
If I create the same RAID array, I will loose what is now on the disks I guess, no? I will try it when I'm ready to format the disks again..
In fact I cannot enter the recovery Menu, only "Esc" works, not the arrows or Enter. So I can't see if in the Recovery Menu, I can put back a Non-Raid Disk as Member Disk.

Thanks for your advice, the raid driver's world is dark for me

It's windows 7 64.

I will keep you intouch if I find a solution
