? Can I restore AHCI Image to a RAID-0 array?

Thread needs solution

I want to know if I can restore my current image of a single SSD running in AHCI mode with OS on it, to a RAID-0 array on the same platform once built.

I recently purchased an additional SSD and to improve performance and increase storage space I want to Raid it with the existing drive.

My system is built on the x58 chipset and I'm using the ICH10R controller for the single drive and will use the same for the RAID-0. The most current IRST is running with the OS which is Windows 7 pro x64. I'm currently running ATIH2010 (7.160)

Any tips precautions, instruction, or hints appreciated.

This is typically a nightmare situation.

Interestingly, I googled around to find this article:
http://forums.hexus.net/hexus-hardware/112584-how-enable-ahci-raid-mode-without-reinstalling-windows-p35-ich9-ich9r.html

So have a read. You might have a path by restoring on the SSD in IDE mode and then tweak your BIOS settings and registry according to the article.

If this works, verify that Windows has properly recognized the SSD automatically:
- the SSD should not show up in the scheduled defragmentation setup,
- the superfetch service should be turned off,
- the TRIM function should be activated.

I'm familiar with the registry switches. AHCI and RAID mode are synonymous both enable smart features and hot swap capabilities. The only major difference is one you can build RAID arrays and enable the option ROM at boot and the other not so much. With my goal being to restore to a RAID array I don't see how switching to IDE would help me as it would be even further away form what I need. I simply don't see the path you are referring to. I know I don't need additional or special drivers for the Intel RAID as they are native to W7 and in theory if I switched to RAID now I should be able to boot so maybe I'll try that. What I don't know is if the bootloader can be repaired by the installation disk to make it bootable in to the RAID array. I guess I wanted to hear from someone whose been there done that. My TRIM is active, Ive turned off superfetch, defragmentation and a host of other optimizations were used from the get go with the original drive.

Right. I completely misread your post and somehow figured were migrating from a single traditional disk to 2 SSDs.

My response is irrelevant.

I remembered some mention of your path (migrating to RAID 0 from an AHCI configuration) when I put my DX58SO system together.

I didn't try it myself

I would just try it and see. I think it should be just fine since it's the same driver. It shouldn't be any different than switching the controller into RAID mode and not defining an array. The single drive would be seen as AHCI.

TI should adjust the BCD file so Windows can boot. Otherwise, you would need to boot the the Windows 7 DVD or System Repair Disc and do a repair. Assuming the drivers are included in the standard discs, this shouldn't be a problem. A RAID "drive" is seen as a normal drive.

Thanks to both of you for the input!

Looks like I might be able to migrate to RAID-0 with the Intel® Matrix Storage Console which would be nice but when the Raid volume is created all data will be lost regardless so restoring the image is my paramount concern. Unless I'm mistaken and the console manages to migrate the data at the same time it builds the array.

The process is further complicated because my firmware doesn't match and I have to update the old (OS) drive to the new firmware before creating the array. If I'm lucky enough to flash the drive and it comes out on the other side fully in tack (bootable) this might be a viable solution.

I think the whole operation may be further complicated by the fact that I used the default W7 drivers at the original install vs loading the Intel drivers through the F6 command. Please correct me if I'm wrong. The IRST is a windows environment management tool so I'm not sure how this plays a role.

The worst that could happen is I'd have to format and reload which maybe the best solution in the end anyway. Like most who buy imaging software I want to avoid the reinstall hassles so if there is a way path I want to use it but I've already wasted enough time that I could already had it done. Maybe in the end though I might save others the time and effort so I will report back how it goes.

I've never bothered with installing or using the Intel software. I've always just configured the BIOS and RAID and leave it at that. I haven't had any problems using the Windows supplied drivers. You can do conversions and such with the Intel tool, but I've never needed it since I just change RAID and restore an image. Since I want a backup anyway before making those types of changes, it's probably just as fast or faster to restore.

@owcraftsman,
Plase have a look at Topic# 36709 i have created.
Do you have finally succeed your AHCI to RAID 0 migration on your side ?

As I recall, I moved all my data to other drives. Wipe both SSDs to restore to factory condition. Then flashed the newest firmware on both drives and installed windows clean in AHCI mode RAID-0 on the ICH10 controller. The system still boots in under 30 seconds. As for ATI home it's to unreliable for anything other than data backup. It has failed me many times Home 2010 and 2012. However good luck to you. Had trouble finding the post you mentioned a link would have been better.
