I have a box with Gigabyte MB, and EZRaid/IRS RAID technology on it. I have 1 OS and 3 data disks installed (lets call them D1 D2 D3). Inadvertently (just hit the space bar twice and that was enough...), I created a RAID 1 volume with D2 and D3, which happily wiped D2 and D3 of all the data in them. It did that very quickly so I am pretty sure it mostly (hopfully only) overwrote the disk metadata.
I undid the operation, which included reverting to AHCI (this was done in the background I believe), which left me with 2 "empty" disks. Incidentally, I could not access the boot disk either until I reverted to AHCI.
Now I want to try and recover the volumes on the 2 disks, is there a "standard" way to do that? What part of the disks are written by the IRS sofware when it creates the RAID 1 volume? Does it overwrite the partition label only or also part of the data? Unfortunately I don't quite remember if the 2 data disks were formatted using MBR or GPT labels. Any pointers would be appreciated.
Thanks for the answer. I believe the page you linked is for this scenario:
Instead, *my* scenario is this:
Hope this explains it better?
