    Access to both "fake RAID" and SATA drives

    I have a multi-boot system with kubuntu 10.10 plus Win-XP and Win-7.
    All three OS are on the same SATA drive, in the system I have another SATA drive plus a "fake RAID" made up of a pair of SATA drives configured as a RAID-0 stripe.

    During the kubuntu installation process (using the alternate distribution CD image) the RAID array is detected ("one or more devices containing Serial ATA RAID configuration detected. Activate? Yes/No"). If I select "Yes", then only the RAID array is detected and installation would only be possible to the RAID array. If I select "No", then only the two SATA drives are detected - I chose this so that I could install on the boot drive. Now the installation works fine and I have access to the other NTFS partitions on the two SATA drives, but not to the NTFS partitions on the RAID-0 drives.

    Does anyone know if it is possible to have both fake-RAID and SATA access at the same time and if so, how to do it.

    config details:
    own built desktop PC
    processor - AMD Opteron 146 2.02GHz
    main board - ASUS A8N-SLI Premium
    memory - 2GB DDR
    graphics -NVIDIA GeForce 6600GT

    disks:
    RAID-0 NVIDIA controller (2 x SAMSUNG SP250) total of 500GB
    SAMSUNG SP250 also via NVIDIA controller (set as first boot disk in the BIOS)
    SAMSUNG 500GB connected via SiImage controller (seen as SCSI )

    13 hours, no help ....

    OK, I'll try.

    Without doing 1 millisecond of research, I will offer an unsubstantiated assertion that there is no Linux driver available for that Nvidia RAID controller. If that is true, then you are NOT going to install Linux on a RAID array on that motherboard (unless you go with mdraid, after making a serious study of the subject, starting someplace like here).

    So, you can install Kubuntu on a partition on a single SATA disk. Or not. But you can't install it on a RAID array as controlled by that Nvidia RAID controller (or the Silicon Image controller either!).

    Sorry.

      There is driver for nvidia fake-raid for Linux since ages....
      And Ubuntu have built-in support for dmraid since 9.10 so You no need to use alternate Cd.

      As I uderstood You have for drives. Two sata separately and two sata connected as raid. Is it?

        Yes, disk configuration is two disks as a RAID-0 pair and two disks as JBOD (normal SATA).
        I used the alternate CD for the installation, but it detects the RAID array and asks if the RAID support is to be enabled. If I say "Yes", then it installs onto the RAID array and the two SATA disks are not accessible. If I say "No" then it installs onto a SATA disk and the RAID array is not accessible.
        I want to continue with the current installation on the SATA disk, but how do I enable the driver for access to the RAID array in addition to the SATA disks?
        Thanks for the earlier reply.
