travaux parfaitement sur mon windows 7 64bit norvégien!

works perfectly on mine!

Thanks a lot !

I used Peregrinus hint and it worked perfectly for me (on Windows 7 x64). I guess the reason why it doesn’t work for some people is, that they had AHCI activated before. To deactivate you have to set HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\msahci\start to 3 (should have been 0 if active). Although I didn’t try it I think you are only allowed to have either msahci or iaStorV active. Maybe you want to give this a try if Peregrinus instructions won’t work for you

If you had a spare disk sitting around, I would try cloning your OS drive so you have a backup, then giving the RAID configuration in the BIOS a try. I know it states that it will destroy all of your data, but that sounds like it is a simple “catch all” warning that Intel chucked in there just in case the configuration process blew your data away.

I personally have configured RAID 1 arrays after installing and configuring Windows on an ICH10 controller without any problems at all. Not a single byte of data was lost.

Instead of extracting the iastor.sys from Intel(R) Matrix Storage Manager as you described in this new and the previous method.

Simply download the “32-​​bit Floppy Configuration Utility”, the file is inside the zip file

I am trying to create it in Windows, I only mentioned Linux because Windows and/or Intel seem to be making this 100x more complicated than it ought to be.

In any case, I thought that the whole point of this method was to make the RAID work after Windows was already installed. When I try go to set up the RAID early on, immediately after BIOS, the tool tells me it’ll destroy all data on all disks, something I was hoping to avoid. Did I totally misunderstand the goal and techniques laid out here?

Where are you attempting to create your RAID volume? You mentioned that this is typically a 2-line operation in Linux, so I am guessing that you are trying to create the RAID volume via Windows, correct?

I typically shy away from doing it in Windows and instead configure my arrays from within the RAID controller’s BIOS, before Windows even boots. You will typically see a message similar to “Press Ctrl+I to configure RAID” after your computer’s BIOS messages pass, but before the Windows loading screen appears. I recommend configuring RAID there – you might have better luck doing it that way.
