In order to rebuild your RAID you need to boot to Windows or to the Operating system you are using. Then, access the Intel ® Matrix Storage Console and choose the rebuilt option. For additional information you may want to check this link. http://download.intel.com/support/chipsets/imsm/sb/imsm_reference1.pdf
In the other hand, I will like to inform you that we are now using the Intel® Rapid Storage Technology, so I would recommend you to update this software once you rebuild the RAID. You can find the download file on the following link:
Thanks for posting the location of Intel Matrix Storage Reference V1.0, it answered a question I was just about to post to the community.
(I was going to ask "how can I re-instate a raid 1 array when I've previously reset the array back to non-raid because of a faulty disk". Yes, I now realise that I needn't have reset the array, but as it turned out, I was able to diagnose the flakey disk using a competitors SMART monitor (Acronis) only after resetting to non-raid, and switching back to AHCI, I think. I've since purchased a new disk, and was wondering how I'd install it, given the situation I've got myself into. But I think I'm OK now. )
(PS: if anyone wants that translated into English , I'll re-write it when I have more time. )
i have the same problem but there is no indication to 'Rebuild' from the OS.
i just have the failed drive listed. i've add my new drive but it doesn't show in the OS. when i reboot i can see the new drive using the RAID BIOS Ctrl-I option.
