Trying to recover partition after Intel RAID messed-up
Posted: 19 Aug 2014, 10:07
Hi,
I know, this question has been posted a lot of time, but I didn't find all the answers I'm looking at.
So, I've an Asus Z97-Deluxe, when I update the BIOS, I always have a RAID0 that failed, but that time, I totally forgot this issue and I cleaned-up my backups from my NAS 2 weeks ago ('-_-).
So, I try to use some procedure on the net, mark all disks from the array to "Non-Raid member", well, was just one of the two drives in fact, then, I recreate the array, same name and parameters as before.
Disks are still connected to the same SATA ports, I didn't try to change them.
When I run Testdisk (from UltimateBoodCD, should be version 7 of TestDisk, not at home right now), I select the MD126 (which is my Intel RAID array).
TestDisk detect the "EFI GTP" partition type, which should be correct as I use the Windows GPT partition type on Windows for all my recent install now.
The RAID0 use 2x1TB Samsung HDD, and for the CHS, I have something like 4 2 for H and S, I don't think this is normal, so I change that to 255 63 but I only find EFISECTOR, boot or similar, never find any NTFS partition (even with Deeper search).
If I select "PC/Intel" partition type, changing the HS values to 255 63, I find 2 partitions, one that I deleted, and one that seems almost correct (not the good size, but still have a big part of the datas), but it still miss one of the partition, even with Deeper Search, I didn't find it.
After that quick Analyze, it tell me that the Heads size should be "64", so I also try with that value, no big changes, same results.
So, question: What can I do ?
- Change the SATA Ports ? (don't know why I should do that anyways)
- Calculate a better "CHS" value, but don't know how to proceed with an Intel based RAID0
- Put some C4 on it and push the red button... (last resort)
And which partition type should I use, "EFI GPT" or "PC/Intel", as it should be in GPT format but I've a doubt.
Thanks for your precious help (I try for 3 days to make that working, I'm running out of solution...)
