Need help with new RAID0 install with my dual boot AHCI devices.

Need help with new RAID0 install with my dual boot AHCI devices.
« on: November 16, 2012, 11:11:52 pm »
I have picked up 3 OCZ 120GB SSDs that were on sale for $55 and decided to make a RAID0 win7 boot drive.  I disconnect all drive and install win7 from usb stick to my striped raid0 128kb drive with no issues at all.  Didn't even need to load the F6 raid drivers.

After all setup and updated I now cant boot my other two win8 drives that were formatted with AHCI and and now considered non-raid array drive.

I thought AHCI was still compatible in raid mode?  I see no way to load a raid driver manually.  I have IRST installed on both of my win8 installs, which I would assume would support AHCI, as well as, RAID?

Is there a way to inject RAID in win 8 pro w/ MCE?

From the days when i did it with 7 and vista you would have to load win 7 first then install windows 8 as the bootloader only works with newest os first then oldest. As for achi and raid if you have 2 different controllers you can do it by using one controller for the raid and other controller for achi if you dont have two different controllers i dont think it will work.

Now a work around is set bios to raid when using windows 7 then boot. when you want 8 just set bios to achi and it should start in windows 8

I don't have a multi-boot loader.  each hdd has it's own full install.  I use F12 to switch hard drives I want to boot.

I just need to know how to enable RAID in AHCI mode.  Much like setting ide/sata with registry or something?

I've done this before, but I can't remember how.

Also, I switched to AHCI mode and booted from my windows 8 partition and when I switched back to raid one of my drives came out of raid mode for some reason.

I am waiting until I can enable RAID in my win8 AHCI drive before attempting RAID0 reinstall again so I don't lose raid again.

Thanks for you help

to clarify, I currently have 1 SSD with win 8 installed in AHCI.  I now want to just basically add a pair of SSDs in a RAID0 configuration for data.  Then I should be able to make the RAID0 a bootable disk after the fact.  The AHCI will be in a non-raid array.

I got it working.  The only successful messages I found were people using two controller, which basically allow you too boot both ahci and raid.

I couldn't find my spare controllers anywhere, so I went through the bios to see if I could figure out a setting somewhere and sure enough it said I had a marvell controller, then I realized this board has mSATA and eSATA and luckily I had an eSATA to SATA cable in my home server and borrowed it and put my ahci drives on it and then booted mu ahci drive and it went without a hitch.

I didn't even get a new hardware found or any discover dings at all.  It just enabled RAID0 automagically.  It must have made a registry tweak somewhere as it didn't load any special drivers.  I wish I knew what setting was set in case this happens again.

But everything is working fine.

Thanks
