RAID 5 Issue due to extra character addition (:0) in my Raid info

[mweddy]

I was having Asus sabertooth x58 board on which i was using Raid 0, Raid 5 on 3 *2 Tb Seagate sata drives.

My raid configuration was:

Raid 0- 64 kb stripe- 60.1 Gb - For windows 7
Raid 5- 128 kb stripe -3.5 Tb - For Data (Partitioned inside windows as 500Gb, 800Gb, 1 Tb, 0.9 Tb)


My hdd model no is ST2000DL003-9VT166 and serials are :
Disk 1: 5YD43065
Disk 2: 5YD3ZXFL
Disk 3: 5YD44G0F

Raid information is stored as :
Disk 1: 5YD43065
Disk 2: 5YD3ZXFL:0
Disk 3: 5YD44G0F:0

Note that raid 0 is created from 3 drives not 2.

I sold my board and purchased a new Asus Sabertooth Z87 which is also having same intel raid hardware .I connected the 3 drives in same sequence. Put my raid settings from Bios menu.

But when i rebooted my PC, my raid status was Failed. My 1st drive is detecting as RAID drive rest 2 are non raid.

So i asked my buyer to let me check if i can recover my data on old Asus Sabertooth X58 but same results as in new one with same sequencing of ports and drives.
only the Old motherboard driver is 10.something version (not remembering exactly) and new one is 12. something(latest).

So to recover i used R studio software used to recover raid data on a different drive having windows 8.1 installed in IDE mode, somehow i managed to recover 60 gb data of Raid 0 which is mainly windows 7. But my important data was in 3.5 Tb partition of raid 5 which i am not able to read via this software. Conclusion is that R studiio can read 1st Raid ie Raid 0 of 60 Gb but not afterwards.

So i installed windows 8.1 in another drive with Raid mode and installed Intel storage matrix software for riad version is 12. something and i saw that Raid information for my drives. Same here 1st drive reads Raid and rest 2 drives saying unknown. But drive serial is like Serial:0 for both drives. Here :0 is appended to raid info so none of my 2 drives are readable by raid hardware.

So i searched net and found that if i somehow i change my HDD serial number of 2nd and 3rd as required in Raid, it will detect raid drives and i can rebuild
This is possible if I can change one HDD serial number.

Or if i can change raid information from Drive 1, it can read my remaining two drives.

Please help if this is possible. I will be grateful if anyone can help.
This is one of the issues in Intel raid drivers of appending ":0" to raid drives.

Disk 1: 5YD43065
Disk 2: 5YD3ZXFL:0
Disk 3: 5YD44G0F:0

Note that raid 0 is created from 3 drives not 2. Because once i removed one of my drive and my raid failed and again after reconnecting it rebuild the whole data again.

I sold my board and purchased a new Asus Sabertooth Z87 which is also having same intel raid hardware. I connected the 3 drives in same sequence. Put my raid settings from Bios menu.

But when i rebooted my PC, my raid status was Failed. My 1 st drive is detecting as RAID drive rest 2 are non raid.

So i searched net and found that if i somehow i change my HDD serial no as required in Riad it will detect raid drives and i can rebuild even if it possible to change only one HDD serial.

Or if i can change raid information from Drive 1, it can read my remaining two drives.

This is one of the issues in Intel raid drivers of appending ":0" to raid drives.

Those Seagate drives are prone to firmware/system area corruption. This is common failure for those drives.
That's why the serial numbers are modified.
There's nothing you can do to fix that kind of corruption on your own safely.

$1500 is what you need. That's how much a professional lab will charge minimum to recover your data.

You've proven the RAID0 data is recoverable. So I suspect it's the case that you are not supplying the correct RAID configuration parameters to R-Studio to recover your RAID5. R-Studio should not care about serial numbers. If you can't figure out the correct parameters PM me I may be able to help.

Note best practice is to make clone images of each drive and perform recovery work on the clones.

Also it's a good idea to check the SMART data on the drives to see if there are any problems.

As u can see that 3* 2 Tb is not easy to clone it is more expensive
And R studio is automatically accepting my raid as Raid 0. That is correct and I recovered that data but on the same 3 disk I m having Raid 5 also which R studio not able to detect. Now tell if u can help me U are the storage expert.
Smart data is accurate. Only my Raid information was changed due to Intel issue of appending :0.

Yes, please help to find correct raid parameter.
If possible give me simple answere on how to change Raid information which is stored in Disk 1
Or
How to change Serial number of Actual hard drive (Seagate) without data corruption.

Rest I will manage.

It's not recommended to move drives between hardware raid controllers unless they explicitly state that they are compatible. There is no "standard" for raid.
