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!
@raid-dingue :
Welcome at Win-RAID Forum!
Yes, it is not the best location for your help request, but we can leave it here until we know the exact reason for your problem.
This Intel RST(e) driver version was not a good choice. Much better would have been the Intel RST(e) RAID driver v13.1.0.1058 WHQL (look >here<).
Additional question:
Which Intel RAID ROM/EFI RaidDriver version is running?
It would have been better to avoid any overclocking as long as your system contains a RAID array.
This is what I suspect as well. It was a big mistake to start Windows while creating a RAID array.
This is what I would do:
1. Enter the BIOS and restore the “optimized default” RAM and CPU settings (no overclocking).
2. Backup your important data.
3. Flash a BIOS, which contains an Intel RAID ROM/EFI RaidDriver version, which matches your in-use Intel RAID driver version (should belong to the same development branch).
4. Boot into the OS and install the Intel RST(e) RAID driver v13.1.0.1058 WHQL.
5. Enter the Intel RAID Utility (via CTRL+I or “Intel Rapid Storage Technology” tab within the BIOS) and try to create the desired RAID array. If this should be not possible, you will have to do a low level RAID reconstruction.

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 
The change of the Intel RAID driver version is not really necessary now. It will not solve your problem.
Note: As long as the new RAID driver supports your Intel RAID Controller, a driver update or downgrade is not risky at all. Furthermore it is no problem to return to the previously running driver version, if you are not safisfied with the new one.
The best matching Intel RAID driver for your currently running Intel RAID ROM v11.0.0.1339 would be the v11.0.0.1032 WHQL, but I don’t recommend to install it, because other Intel RAID drivers are much better for your system.
My suggestion is to solve your current RAID array problem as first step and then think about an update of the Intel RAID ROM (my tip: v13.1.0.2126) and the Intel RAID driver (my tip: v13.1.0.1058 WHQL).
By the way: Which Windows Operating System are you running?
It’s windows 7 64.
I will keep you intouch if I find a solution
