Knowing you spanned the drives without parity or backup, there is no need for me to review the errors. I agree with your tech. Unless there is a miracle (or you outsource the entire array to a recovery location), good luck. Sorry I couldn't be more help. FYI...when you span drives, your single point of failure is an exponential factor of how many drives you are spanning. I have done low level disk data recovery before, but describing it is beyond what I can do via email. Even still, said disk recovery still relied on the ability for the heads to read off the platter. If I were you, I'd consider your backup strategy now for that 7TB array you are building. Thats a lot of data. You need to be able to go back more than one day. If nobody else has a suggestion to retrieve the info, you will send it away. Steve
