Reading from RAID 0 SATA without a compatible controller

My DELL XPS 700 came with nVidia C19/MCP55 chipset motherboard. My two 340GB SATA  disks were set up with RAID 0 (stripe).

The motherboard died and my external back-up has gone awry, and I am looking at two perfectly good SATA disks with perfectly good data on them, but don't know how to get the data off.

DELL told me that they are not able to provide a replacement motherboard. They offered me a deal on a replacement system, but said that they do not do data recovery and that I cannot get the data off my disks, but recommended I try a local data recovery expert. Local data recovery experts said that you cannot get the data off the disks without using the same motherboard, and that I should go to DELL. Bah.

The data is valuable. Do I have to find a nVidia C19/MCP55 motherboard to access it (e.g. from eBay) or is there another way that I can get my data from the stripe?

Buy runtime.org's reconstructor software  (you can try it for free, just to make sure it works and can put it back together).  This will strip off the metadata, and logically reassemble it into a single 680GB disk.  This will be a pain because you will need a single 750GB (or larger) disk to put the reconstructed target on.  

Or, as crzy said, buy another motherboard with same chipset (WHICH MAY ALSO NEED SAME FIRMWARE).

really the only way to do it is to find a motherboard with the same chipset/raid as your old one. so yes, it looks like ebay is the answer.

Thanks, chaps. I'll try reconstructor software, because it looks like the motherboard is difficult to get your hands on.

BTW - those local recovery "experts" who said you can't get the data should be avoided.  Heck, I could get it back in about 15 mins with nothing more than a linux box and a few minutes writing a shell script using the dd command, and any data recovery firm should have people who can do this too.  Don't give them any business in the future, and I would make it a point to tell your friends and associates to stay away from them as well.  Amazing that they can't do something as simple as this!

If you knew the drive geometry (sector size etc), are you saying that DD could generate a disk image from a stripe? I assume runtime.org's software value is that it sniffs out the appropriate geometry.

Yes, but there is more to it than that. You have to fix the partition headers, and use a shell script to reassemble the stripes and properly deal with any unreadable chunks.   Don't even go down the path of thinking you can do this yourself.  I've been in the biz 20+  years, so know the internals.  Anybody who says they do recoveries should *know* the internals of NTFS and have software that can do this, that was my point.  This is not a DIY, because you have no idea how the data is interleaved between each stripe.  With the right software it is relatively easy to find out, but such software is usually written in-house, over time.   You won't find this stuff out there for free. It is too valuable.
