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:
- System with 2 disks in JBOD configuration (say D1 and D2), and each contain a filesystem (FS1 and FS2) with data
- a RAID-1 volume is created (say D3) and formatted (FS3). At this stage the new filesystem is empty
- the user writes data on FS3
- The user follows the procedure you linked and goes back to 2 independent disks
- In each disk FS3 is still present and files can be accessed.
Instead, *my* scenario is this:
- System with 2 data disks (no boot disks) in JBOD configuration (say D1 and D2), and each contain a filesystem (FS1 and FS2) with important data
- a user (that's me unfortunately...) creates by mistake a RAID-1 volume (say D3) but does NOT format it. At this stage the volume (D3) is empty, with no filesystem
- the user wants to revert the operation in order to have access to data stored in FS1 and FS2 again
- The user breaks the RAID-1 volume and tries to mount the volumes. However, no filesystem and not even partitions are detected by Windows, in any of the 2 disks. And this is where I am at :(
Hope this explains it better?
