I am an individual user of HP P212/Zero Memory Smart Array Controller and I have a RAID5 on it.
This Raid5 contains 6 Seagate 2TB SATA Hard Drives, no hotspare. It is working with a battery and 256MB RAM.
Just now there were 2 hard drives (The last 2 drives in the array) lost from the array by unknown accident. But I am sure that the 6 disks are all working well by themselves. They should not be broken or damaged.
I restarted the computer and the 2 drives were back into the controller while the logical drive (the raid5 array) still showed loss. In the control panel there is only option to delete the previous array to build a new one.
However, I cannot lose my data (about 9TB). I hope to find a way to recover this RAID5 with my data preserved.
I know, as the data were not damaged - just lost connection from the controller, there is a common solution that I need to mirror all the disks using some software like WinHex and rebuild the array on software platform and get all the mirror copied, but this solution requires skills on dealing with partition tables which I am not good at yet. I hope to get some help before taking such risks.
What about R-Studio? Do I need to disconnect the disks from the P212 controller and connect them with my motherboard to access them as single drives?
I wish professionals working on server storage technologies could help me with some good solutions.
Thank you very much.
