I have been doing raid data recovery for many years. A very common scenario is "Two Drives Failed at Once". This is usually not the case. What usually happens is 1 drive fails. The raid then goes into degraded mode and continues to function. Nobody notices the warnings. Some time later... months or years even, a second drive fails, the raid goes down - now they notice. They call in the techs who declare 'two drives failed'. This is when your data is most at risk. People start swapping boards and drives, repower the system, rebuild drives, rebuild parity, force stale drives online etc. I have seen alot of raids that would have been recoverable had they done the proper steps. Then they hand it over and say they found it this way... didn't touch a thing...
