Once in a while a hard disk within a RAID-1 setup fails and one wants to recreate the RAID to get data redundancy again. As useful documentation on my onboard RAID controller is not available, I wrote the following to the ATI/AMD tech support:

Dear Sir or Madam,
on my motherboard (Asus M3A32 MVP Deluxe) is a RAID controller (ATI SB600) present. Until one HDD crashed I had a RAID1-configuration. I removed the defective drive and replaced it some days later with a new one. Now I am wondering, how to restore the RAID-system?!? Is the RAID system rebuilding itself? Do I have to delete the RAID arrangement and define a new one? Or is all data lost, when defining a new array? On the Linux system (Ubuntu 10.04.1) I had no extra drivers installed for that controller.

Some days later I got an answer from tech support telling me theoretical stuff I already know but no practical help at all as you can read now:

Regarding the question " motherboard (Asus M3A32 MVP Deluxe) has a RAID controller. One HDD crashed, I removed the defective drive and replaced it. How to restore the RAID-system?"
Unless you have a mirror image raid, there is no way to restore the Raid.
Regarding the question "Is the RAID system rebuilding itself? Do I have to delete the RAID arrangement and define a new one? Or is all data lost, when defining a new array?"
You will need to rebuild the raid.
As for you data we don’t know what setup you had and cannot determine the condition of the data.
You may need to research that option on the internet, or try data retrieval.

As this information was of no use what so ever I decided to reply to that mail describing my problem again with some other wording with the hope that my intentions will be more clear to the tech guys at AMD:

Dear AMD Global Customer Care,
thank you for your quick response. Unfortunately your answers were not very helpful. So, please let's try again:

I had a RAID-1 Mirror setup on ATI SB600 controller with two identical hard disks. After failure I replaced one disk with another identical one. That means, on one disk is still all the data.

As there was no documentation available on CDs or the internet on how to rebuild a mirror RAID with this controller, I'd like to ask you about more details. Please regard in your answer, that I am using Linux.

Thank you and best regards
