Recovering RAID0 Data

ronyan · Mar 21, 2014

I have a RAID 0 array of 2 ssd's with two identical 180gb ForceGT Corsairs that has been running well under Windows 8 64-bit. I was using them to install and run games on but running the OS on a WD 640gb seperate drive. However, under windows 8 I was having stability issues with a few games I wanted to play in steam...not related to the RAID, they were running good under Win 7 64 with the same RAID configuration.

I chose to downgrade back to Windows 7 (64 bit) in order to play the games, and stupidly backed up some of the data to the RAID 0 array. After re-installing the Windows 7 64b, the array is not recognized properly. In Disk Management, both ssds are shown separately as Healthy, Primary Partitions with no drive letter assigned. I'm unable to see the array as a single volume in explorer. The only option available for each drive in Disk Management is to 'Convert to dynamic disk'.

The motherboard I'm using is a Gigabyte GA-Z77X-UD4H, have already installed the RAID drivers for Windows 7 from Gigabyte's site and fully updated Windows 7.

Looking for a tool to recover the backup or a solution that will allow me to use the arrary in Win 8 without formatting and losing my data. thanks

There is data recovery software out there that can reconstruct a stripe set into a single raid volume, however the bigger issue is that the drives are showing up partitioned.
If the drives were mounted into windows and repartitioned independently, then there is a good chance that file system data pertaining to the RAID has been corrupted.

The first thing you'll want to do is make sector by sector images of the 2 drives then you can try software like RAID Reconstructor or R-studio working with those images. Whatever you do, don't work with the original drives, as you'll risk further corruption.

Rstudio is pretty simple, but it does require some intermediate understanding of file systems and stripe pattern analysis if you've got issues with corruption.

Your best bet is to get a professional data recovery company to do this, but I would ALWAYS make images for yourself just in case first.

There are companies out there that will do it for $300-$500 per drive, but they are literally bottom of the barrel and don't make any images before attempting to reconstruct the RAID.
A more professional lab will charge you twice that typically but they will make images first and have more talented engineers that can deal with various issues with corruption.

Try using the latest Intel® Rapid Storage Technology (Intel® RST) RAID Driver first: https://downloadcenter.intel.com/SearchResult.aspx?lang=eng&ProductFamily=Software+Products&ProductLine=Chipset+Software&ProductProduct=Intel%C2%AE+Rapid+Storage+Technology+%28Intel%C2%AE+RST%29

Hi Ronyan, I'm sure the professional version of stellar data recovery software will help you easily recover the data from RAID0 to RAID5, you can view its features and download from here http://www.stellardatarecovery.org/stellar-launches-windows-data-recovery-6/
