Raid 0+1 recovery

[dylanb]

Hi, this is my first post so i thought i better say hi to the community

I would like to hear some of your opinions on a problem i have...

I put together a system a couple of years ago built on a DFI lanparty nforce4 ultra D and it has just died, from what i can tell the mobo has packed up. My problem is I had 4 x 40gb drives in a 0+1 raid array(i thought they were in raid 5 but looking back at the boards specs it only supports 0,1,0+1, so i can only assume it was 0+1).

Now i'm desperatly trying to recover the data, but there are few things im unsure on;

Can i try to recover a raid 0 array from drive 1 and 2, or 3 and 4 ?

Do you think another nforce4 ultra based board it likley to read the array properly? as the ultra D is proving hard to replace!

does anyone know of any software that will help recover these drives without trying to setup another nforce4 rig?

any help would be really appreciated!

the problem with built in raid is it tends to need the same chipset to get it back, shouldnt cost much for that spec board though.

The way raid 0+1 (often called raid 10 (1+0)) worsk is that you have 4 disks, a pair in raid 0, so the data is writen across both disks, then the 2nd pair also in raid 0. these two raid pairs are then put into a raid 1, so the data is copied on both raid pairs.
AFAIK and disk from a raid 1 array will work out of the array without issue as they are just stright copies.
The problem here will be figureing out which pair of disks belonged to which of the two raid1 arrays.
Then finding something that will read the raid1 array off a pair . . . not much help here as I've never uesd a raid1 array or tried to recover the data off one :

Got it all recovered, for those who are interested, after trying many apps, 2 did the job: raid reconstructor & getdataback for ntfs. and yes, you can restore raid 0 arrays from a raid 0+1 setup, by that i mean, i had 4 drives set up as raid 0+1, drives 1&2 and 3&4 can be used alone to restore the original disk image
