Hi,

We have a problem with a HP Smart Array P800 with 25 HDD, ext3 partition.

We have found (we think):
- order HDD (1 to 25)
- block size (16 kb)
- RAID 6 (ADG)
- Parity left async.
- stripe size jump (16)

We have on the first hdd:
- sector 0 => the MBR
- sector 1 => EFI PART
- sector 2 => 1 descriptor table, start 0x22 => 34

Problem:
- we can't view ext3 partition

We suppose, there is a offset on HDD 2-25 but how many but 0 offset on HDD 1 ? It's possible ?

Any idea are welcome.

Bye

try to create new 4 HDDs raid for test. and look on the data

Yes I want... but I have only HDD... not the bay....

Nice one

I guess you were trying to figure out it in UFS Explorer? Right?
As i know it couldn't build Raid6 with delays .

You have only chance to figure out it in R-studio
But , it is don't know correct Raid6 configurations for HP
So, only manual work in R-studio .
But... your array will have ....25*16=400 sequences
and 9200 cells

Yes, it's true

Do you want the XML... we have build a software for build this xml...

No thanks, i have it



I don't get , you have built or still building ?

Thanks....

First 166 rows...

But I you have an solution, it's better....

Almost fine except one mistake (will not work if you will be missing one or two drives) .
And show us the last 16 sequences, there is some trick too.

Looks good. End right.
Have you found offsets already?
Usual 1088
And, as i hinted you before , interchange XOR and Reed-Solomon (will help if you have missed disks).
