Help with raid 5 recovery after bios setting change made disks go nonmember. $50 reward

post #1 of 8
Thread Starter 
TL:DR Bios setting was changed made Intel bios clear the raid settings. Made new raid with what I think to be the same 128 cluster size. Booted in to windows where intel RST started initiation stopped this at 1-2%. Have not be able to recover anything but very small files like notepad from the drive.

I'll paypal the person that leads me to recover my data. $50. Please help lots of photos year.

System:
i5 ivy bridge
z78 extreme 4
4x 3TB Seagate harddrives in Raid 5 and an agility 3 120gb ssd on the intel sata

What caused the data loss: I was in the process of installing a new SSD and cloning it over to the new drive. The migration software was not compatible with the intel chip set being set to raid. I changed it to either ahci or ide I don't remember. I completed the migration. How ever after setting the Sata ports back to RAID I found that the intel bios said that all 4 Seagate drives were now non-member.

I did some searching and I found this guide online:
http://www.overclock.net/t/478557/howto-recover-intel-raid-non-member-disk-error

HOWEVER! This guide did not mention that this only works if the OS in on the RAID system and if it is not like in my case my OS in on the SSD after you reboot into windows the intel RST will start blanking the drives. I stopped this before it got too far. Likely it got to 1% or as high as 2 of the initiation.

So this is where I am. I have tried the test disk software, I am not sure if I was using it correctly I tried a few times. It didn't work.

I tried using data recovery software from ZAR (paid). I was not 100% sure of my cluster size so I setup the raid in 32, 64, and 128 and ran the data recovery (an 8 hour scan each). The interesting thing is different folders are recovered with each different cluster size. As in when I run the recovery after setting it to 64 vs 128 different filenames and folders will be recovered. I’m no expert so I don't know what this means. But all files recovered until they are very small are corrupted.

Example: I can see some of the thumbnails of the photos I'm trying to recover but when they are opened they are only the top 5% of the photo and the rest is gray or garbled.

I have tried a few other programs however they either crash or bring back corrupted files. I am currently running with the bios set to ide, ZAR in raid recovery mode set to 128 cluster. It had been running for 24 hours and its only 4% done….


Question: Am I using the ZAR software correctly to recover from my problem? Is there another program that my work better? How much would it cost to send this raid set out to be recovered?

I spent countless hours after one of my HDDs failed trying different tools, such as TestDisk. TestDisk didn't seem to grab everything for me. [see my thread about it here]

I know it may sound cheesy, but I did come across a program called "GetDataBack" which managed to grab ~90% of my data. Some of it was corrupt, which was to be expected. But it managed to grab almost everything that the other programs I used couldn't. I recommend you try the program, make a clone of the HDDs if you can, and then run a scan.

Tried this yet? I haven't used it in years but it should still work.

How do I go about setting this up?

It only sees my raid as one disk? Should I turn raid off and so that windows sees the 4 drives and then try it?

Also this seems to make an image if so I have no where to put a 9tb image of the disks.

Is that directed at me or tsm106?

Hmmm... I think your next step may be HDD recovery professionals mate, unless someone else here can suggest anything.

Well I got it to work. With ZAR 9.2 paid version. It took 10 days or so but I have my photos back. Very happy!

Glad to hear it! It absolutely sucks losing so much data and I bet it's an amazing feeling to get it back smile.gif
