Disaster struck last week and I've taken check of whats left.

I have a stripe raid accross 2 disks (SATA), I have just receieved a replacement motherboard (same model) and wonder what the chances are of retreiving my info.

For information the board is an asus A8n SLI - i sthe raid config tied to the board or the disks.

Does anyone know if I can rebuild or retreive data.

Any ideas advice very welcomed as I have a lot o finformation on there that I would love back (and before you say backup - I learnt the hardway and have now purchased a NAS)

I am pretty sure the RAID array is tied to the controller on the motherboard, but I could be wrong!!

Yeah, pretty much. There will be some config info on the disks but it's not usable by any old controller.

The array may be recoverable, you've got the best case scenario of a like for like replacement however there's no guarantee that it'll come back without a fight. This isn't something I've done so I'm kind of going on theory a bit. I'd suggest making sure that the BIOS on the new board is configured correctly before adding the disks - make sure the SATA ports are in RAID mode etc. Then add the disks and go into the RAID config and see what's what, it may just detect the array straight off, it may not. If it doesn't try swapping the drives over in case they need to be in the same ports as they were. A last resort would be to try creating an array on the drives but NOT WIPING THEM, hopefully this will recreate the array config in the BIOS without touching the data.

If the replacement motherboard is the same (ie same chipset etc) as the original, you should be able to get your RAID back again.

I suppose you would do it something like this, install motherboard etc, power on, enter BIOS make sure settings are the same as those on initial mobo (especially those of HDD), Save and Exit, enter RAID bios, set it up exactly as the initial, save and exit, re-enter BIOS, make sure the RAID array is selected as 1st boot device (and all other settings are correct) Save and Exit ..and hopefully it will boot into your OS.

If I'm not correct here I'm sure some one will put me right. :)
 
Those are my initial thoughts aswell - I've delt with scsi raids with say 20 disks per array and retreived data but thats on exspensive controller snot onbaord ones.

Would it be advisble to image the discs before trying to reseup the array so if all goes bad I can retry.

I'm a bit more confident now other folks are seeing this the way I do so fingers crossed.

Thanks
