RAID 10 FAILURE PLEASE HELP!

Hey all,

I'm really hoping someone out there might be able to help with this problem.

I was running a RAID 10 config using four 1.5TB WD drives. It was running off the intel controller on my ASUS Rampage III Formula.

What happened was the other day after hitting the power button, I accidentally hit the reset button before POST. It booted as though it was a failed OC. no problem i thought. I went into bios and set a couple things and booted. everything seemed fine.

Later that day after waking my pc from sleep mode everything was frozen. I rebooted and thats when the RAID array disappeared. On boot now it no longer shows , and in windows it wants to partition all 4 drives.

At that point i stopped everything i was doing and used a program called ReclaiME RAID recovery to get a 2.72TB image of the RAID 0 set. However the image seems only 90% complete. certain files seem to be missing, while the majority are there.

My question is 1. Can i restore the array (i have the parameters) without re-initializing it? (ie wiping it)

2. Is there any software out there I should try/be using to backup the RAID image?

Any help/input is appreciated. Thanks!

this is why raid should never be considered as a backup. (always back up you raid)

that said does the motherboard have a rebuild function? (rebuild, not initialize)

Your right looney. I should've been backing it up this whole time. Once i get this fixed I'll be backing up for sure.

As far as I can tell, the Intel Matrix storage option ROM utility has options to create RAID volume, delete RAID volume and reset disks to non-RAID.

If you create a RAID volume, I'm pretty sure it forces you to re-initialize. I'm scared to go in and try. Perhaps later today once i've gotten as much data off as i can I'll try it.

Do you think simply loading my bios profile from before would work. When the bios initially reset I only set a couple obvious options, rather than load my old profile. I dunno what i was thinking....

With the BIOS rese, did you also remember to change your disk controller back to RAID? Was probably reset to IDE or AHCI? I have had this happen on a couple of builds after BIOS upgrade or a reset after a failed OC. Boot was all screwed. Went back into BIOS, set the controller back to RAID and found the old RAID setup and booted fine. I believe Intel stores most of the RAID config on the disks. So, try and recover what you can to some external device, then check your BIOS settings.

Also, I believe redoing any RAID in the BIOS boot version will re-initialize the disks. Only when creating arrays within the RST tools in Windows does it allow you to pick a "source" drive to keep all of the info of...

Whaler. Thats what I haven't done yet as I'm afraid to do so until I've tried to backup. So your saying that you were able to just set it back to RAID and have it come back to life with data intact?! If so THANK YOU for sharing. this gives me hope that it'll work when I go to try that after this 2.72TB image finishes writing to my external harddrive....

I'm using ReclaiMe Free RAID Recovery. It seems like a good program, but some files seemed to be missing in the first image I made so I'm not sure if its 100% finding all my old data.

Agreed. I would of stuck with the BIOS recovery settings after making sure the controller was in RAID mode.

This also happens when you update BIOS to a new version, it should keep the setting but sometimes it goes back to default and if you have a RAID array of course things go south till you reset it to RAID.

I roll with sigs off so I have no idea what you're advertising.

 

This is NOT the signature you are looking for.

That's exactly what I did. Changed it back in the BIOS. Saved, reboot, and the raid manager picked it all up. Hope the same for you.
