rejoin broken spanned disks

I have two hard drives that came out of a dead PC. The owner wasn't aware that there was two - obviously the supplier had spanned them.

I tried to recover the data off them buy putting them into a USB cradle and copying but the partition info was screwed. I used a couple of tools to do some file recovery - the most successful being R-studio. It was during this that a guessed the two drives might have been spanned. R-studio has a nice RAID rebuild option that seemed to successfully find the spanned partition and let me copy the data.

However - ideally I would like to be able to rejoin the drives so that I can use imaging software (storage craft) to put the whole working OS and Apps onto another drive/system.

I have put them into another system as second and third drives and the OS sees the two drives - but doesn't automatically rejoin them - I haven't initialised (as windows suggests) - basically I am yet to do anything that will WRITE to the drives.

Any suggestions?

The RAID span might have been part of the controller.
I.e. SATA raid.

Did you let R-studio make changes on the original disk, or did you have it write recovered data to another HDD?  If it was the former, then you can pretty much write off a lot of data. The runtime software is great, but it can't tolerate busted metadata after R-studio attempted repair.

I would NEVER let an app write data to the original disks. I also have disk internals raid Recovery to try out.

First, you've done the right thing in NOT writing to the disks at all -- that's the first and most important rule for successful data recovery.

I'm also assuming from your comments that the disks themselves are good -- they simply came out of a PC with failed hardware.

So ... the simplest way to ensure a 100% recovery would be to re-install the disks in the same make/model of PC they came out of.    Barring that, if you know the make/model, you can look up the specifications and see what the RAID controller was in that model ... likely an on-board chipset based one .. and then attach the disks to any other system with the same controller (or newer downward-compatible controller).

If you don't have access to anything that meets that criteria, then you're already on the right path.   You simply need to use any good RAID-reconstruction tool to recreate the original "disk" that the RAID had created, and save a copy of it.

Note that if the failed system was more than a few years old, you may be able to buy the same model on e-bay for not much more (or possibly even less) than RAID reconstruction software ... so you may want to consider that option.

thanks for you help - in the end recovering the base data was enough.
