Data Recovery from DELL PERC 6i Raid10

Post by wingsoft » Wed Oct 23, 2013 7:42 am

Hi,
we've just buy the R-STUDIO licence in order to recovery data from a RAID10 Array of a Dell PE with PERC6i raid controller
that crashed after a electical crash,.
We've attached all the drive ( no one is damnaged) to a PC for recovery.
Started from "Emergency BOot" the rstudio asked me what to do.

I create a RAID ...
which kind of raid type. I have to choose?
- Virtual Volume Set
- Create Virtual Mirror
- Create Virtual Block RAID & AUtodetect

Thanks a lot

You may learn how to create a RAID10 on our on-line help: RAID10 (1+0).

Thank for your reply.
So I've done everything ok!
I've found a GREEN PARTITION with many others ORANGE with a number.
I've tryed to open files from the Green one ( is it right? ) but ALL the files are damnaged!
What can I do?
Maybe a "Check RAID Consistency" can help me?

First, you should check that the disk order and other RAID parameters are correct.

The Drives are connected in the same order of server
And the RAID10 parameters are the default.
When I click to "Open files" the log gives me a lot of

WARNING : Fixup 2 is ... but should be...


Could be a good idea to click the auto detect of RAID ?
When I click it it gives me " 1 year..." to complete..

No, that feature works only for RAID5 and 6.

About the default parameters:
Are they default in R-Studio or in the server?

NEws:
I've re-check the order of my drive.
Strange thing happened:
- Set (based on Hdd s/n) the order in the backplane in the Server
- If I follow the order 0,1,2,3 nothing appear... If I set my HHD nr 0 to the 4th position, in the RAID appear my partions!!! (also with disk label)

Thanks a good news I hope..!!
But ... I go on to experience the warning:

WARNING : Fixup 2 is ... but should be...

Something wrong with the MFT. It may be a serious problem, may be not, depending on any specific case.
