Hi all,

We have 8 HDD 1Tb from a DX800 NAS.

We think it's one DVRAID but not sure.

Someone know the parity for DVRAID (close to a RAID 4) ?

Thanks you very much.

In reading up on the NAS, it looks like it supports RAID 4, 5 & 6. http://www.jigsaw24.com/sonnet-fusion-d ... duct/12820

Before you do anything, have you done a complete clone of each drive so that you are now working with the clones and not the originals.

I've discovered that some newer RAID controllers store meta data on the drives in a way that it can be read by mdadm in Linux...might be worth taking a look and see. Also, there is no chance that you can read the information from the RAID controller, even to know the RAID type and block size goes a long way.

Exactly, but inside, it's one ATTO Tech Controler R380 card (not confirmed). And this card support RAID 4,5,6 and DVRAID. My best result with data is 512kb with 9 delay parity. But we have many problem with data. Not all a correct.


Yes...

Not find any meta data...

If we can't find correct parameters, my costumer send us the NAS, we put new HDD and send one partern file for detect correct parameters.

Thanks you
