 Migrating two new 1TB drives to RAID 5 array
Using AMD's RAIDXpert, I added two new 1TB drives to an existing RAID 5 array. The existing array already held data. After migrating the new drives (assuming this would allow me to save my preexisting data) and restarting my computer, I am asked to reformat the array. I would really like to recover the data. Is there any way I can do this? From 3 disk RAID 5 to 5 Disk RAID 5. All 1TB.

Software/Hardware used:
Onboard RAID controller ( AMD RAIDXpert)

Answer Wiki:
The data on your original disks should still be avbl. Try removing the new disks. And then reboot.

I just had a similar problem going from a 3 disk array to a 4 disk array.
An odd thing that I noticed is that the new unformatted “drive” is the size of the sum of all 4 disks instead of being the sum of 3 (with the other one’s “space” being parity).
Could block size have something to do with this?
