RAID 1 Options for Windows 7 Home Premium, please help

Ok, I am completly changing my original post instead of starting a new one, situation changed. I realized I can't use Windows Home premium to set up RAID 1. CRAP, CRAP, CRAP - very frustrated :cry: :fou: . Should have done my research. Now here is my question...

I already have these two 1 T drives. What is the best option for Raid 1 (mirror) setup for me knowing Windows Home Premium won't do it for me...

1. Go out and pay another $100+ for windows 7 upgrade?
2. Find a raid controller card? How would that work?
3. Some other cheap solution?

Thanks for any help

  3. Thank you for moving. Anyone know how I might add two drives to my pc? Any cards that do this or do I have to have it run from my mobo. Thanks
  4. Sorry to keep pinging on this, any suggestions? Want to add a raid configuration to my old system, is there a card you can buy that does this?

    Thanks for any help.
  5. Doesn't the motherboard support RAID?
  6. It does,

    These are the available settings:

    RAID Autodetect / AHCI= Raid if signed drives, otherwise AHCI (<<this is the current setting)
    RAID Autodetect / ATA = Raid if signed drives, otherwise ATA
    RAID ON = SATA is configured for RAID on every boot
    Combination = SATA/PATA combination mode

    When you select any other setting this is what you get:

    Attention! Changing this setting may prevent your operating system from booting or require a reinstall. Are you sure you want to continue?

    So that is my problem, I do not want to screw up my system. I have three drives, one little 160MB C drive with the OS, and 2 1T drives that I want to make RAID 1. Can I do this with my Mother Board with out losing my Operating System??

    Thanks for the help
  7. It's pretty tough to answer your question without knowing what motherboard/chipset you have. Based on your settings, you probably don't have an Intel based motherboard.

    Before making changes, perform a complete backup just in case something goes wrong. Then switch the SATA controller to RAID mode after enabling the drivers at boot time: http://support.microsoft.com/kb/975453

    Then you should be able to install whatever tools are available with your motherboard to configure and monitor the RAID 1.

    Thank you for replying. This is what I have and the situation I am in. This is a Dell XPS 400. It is a Pentium D 3000. I installed windows 7 home premium update. I have not changed the BIOS settings I described above yet. I tried to go and install some Dell software for controling raid (somthing the manual says you need after making the bios changes), but because of the windows 7 installation Dell looks at my machine and says "I don't know who you are" and won't install it.

    So, I am cool with switching to RAID mode if it won't touch my C drive, except afraid I will lose my OS because of the warning I received. Since it was an upgrade I am worried Microsoft will tell me that I have to get my original XP installed first on my machine then perform the 7 installation...I am afraid I might not have that windows XP original OEM disk and I might be in a world of hurt.
  10. Isn't there a Microsoft sticker on your system indicating what OS is licensed?

    If the controller is set for "RAID Autodetect/ATA", did you check if HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Iastorv is set to start at boot?

    Yes, windows XP, but I just put 7 on it, Dell servers think its not a dell system. Probably because I did not buy windows 7 from them.

    Current setting, and I have not changed it, is RAID Autodetect / AHCI= Raid if signed drives, otherwise AHCI

    Not sure where HKEY_LOCAL_MACHINE is located, can you give a little more detail?

    Thanks again for your help
  12. HKLM is in the registry (use regedit to view the registry). Please refer to the Microsoft link that I provided.
