I had a RAID 5 array, but two of the drives dropped from the array. (While troubleshooting another issue ASUS suggested I update my MoBo BIOS, but neglected to tell me this would corrupt my RAID config)
I used a 3rd party piece of software to detect the specifics of my RAID configuration:
The data starts at sector (LBA) 0 (this is often called "offset" or "start offset").
Block map is as follows:
1 2 P
3 P 4
P 5 6
Since there were no drive failures or damage (i.e. all the data is physically there), it seems like this is all of the information my MoBo needs to find all the data (perhaps I'm over simplifying this). Is there some way I can re-establish the array without loosing the data?
