RAID 10 disk order identification

[Ajay Kukadia]

Hi all

I have been given 12 HDD pulled from a HP NAS configured as RAID 10. The user did not record the order they were mounted in the enclosure. They are all the same type of SATA disk. How do I identify what the order would have been.
I can mount the disks and view the headers but i dont know where the identifiers would be

Any help would be greatly appreciated

Compare all disks and find your 2 x pairs of 6

Then, use filesystem markers, data references and common sense to determine correct order and block size.

If RAID was correctly synced, then should not matter which 6 you use, as long as all are different. If RAID was not in sync, then you need to match each disk to its relevant set of 6 disks.
