AHCI -> RAID mode, how?

[SteinerKD]

I just built a system using the F60 SSD on a Asus P7P55D Deluxe, as I had read you should do it in AHCI mode I did so and everything have been working fine.

 

Now I have a big problem though, I need to make a RAID and thus need to switch from AHCI mode to RAID mode in bios (RAID mode should still be AHCI), but when I do this Windows bluescreens on load for me.

 

Is there any registry fix I can use to fix this as when you enable AHCI? Or am I stuck without RAID capability/alt have to reinstall everything?? (not an option I want to take right now).

you have to start with a RAID from the beginning, you cant switch after the fact.*

also you must have 2 or more of the same disks to make a RAID and you have specified you only have 1 so a RAID (Redundant Array of Inexpensive Disks) is impossible.

 

*you can image your first disk to another disk then add the 2nd SSD and create a RAID then copy the image to the newly created RAID but you will need 3 disks total and 2 of them need/should to be the the same model.

 

i dont want to sound condescending but i dont think you have been taught anything about RAID or the procedures and materials required to do so. (unless you left a huge part out of your post here.)

There IS a registry hack to convert ACHi to RAID, I'm away from home so I cant give you the link i have bookmarked, I suggest you google "ahi to raid windows 7" or similar stay away from the ones that want you to merge a fiile into registry, its just as simple to do your self.

 

What you do is install the intel RAID drivers, then go into the registry using regedit and change each of the "start" values in the registry keys below from 3 to 0 and this will allow you to change between the different modes by just changing the option in your bios each time you reboot.

 

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\servic es\pciide

 

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\servic es\msahci

 

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\servic es\iaStorV

 

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\servic es\iaStor

 

I can confim this works on an Asus P6T X58 motherboard with Windows 7 Pro 64bit

 

You might not have the last registry key (iastor) as this is installed in the registry with the intel raid drivers, the default windows 7 raid driver uses the iastorV key.

Can and have done, just takes some registry hacking. No need to clone or reinstall.

Yes I left some info out that I didn't think was relevant (what kind of raid I'm building or the number of discs I intend to use) as it doesn't affect my problem, ie, enabling raid mode at all. I now have my RAID0 consisting of 2 SATA2 Western Digital Caviar Black 640GB drives running fine.

I think I have a reasonable understanding of RAID and how it works, what the various levels do etc, just didn't think I needed to demonstrate that knowledge to get an answer on a related issue. My bad, I Apologize.

Thanks, I found an even simpler solution actually. Some tech who ahd been asked this question a few times wrote a little program that will download the drivers, install them and fix your registry (with settings for what drivers you want and if you have 32/64 bit OS). I'll link it here so others can take advantage of it (worked just fine for me).

im glad someone understood you. when i create a raid its done in the BIOS with blank disks and even if they were not blank, they are after creating the stripe. if you said you were intending to use disks other than the f60 you pointed out, i would not have implied you misunderstand what a RAID is.

 

a RAID1 (mirroring) can be done with a full disk and adding another but id like to know (if) how to create a stripe with data still on the 1st disk as i have not seen this done through hardware RAID. you can extend on to another drive through windows but again i did not get that info from your post.

 

at least you know why i answered the way i did now :!oops:

Sweet as bro, I'm glad you found a solution, as I said, I'm always a bit wary of packages put together by others, but that seems to get the job done.

 

makes you wonder why microsoft puts up help pages telling you it cant be done.
