[URGENT] parity in HP RAID 6 Case

[ici_lemmy]

Hello RAID gurus,

I have a case with an HP RAID 6.
There was 5 working drives and 4 defective drives. I was able to repair two of the defective drives.
So now I have 7 working drives out of 9. It should be enough to recover the data.

I was able to verify the type of RAID and find the order, the first drive, the block size and the delay.
So I have almost everything. My problem is with the parities. The first one is a simple XOR, just like in RAID 5 but I don't know (and can't find) how the second one is calculated and it doesn't seems to be Reed Solomon, because when I try that in R-Studio, it doesn't work as expected.

So, does someone knows (and/or is willing to give me a hint) how the second parity is calculated in HP RAID 6 ?
