I don't think your CPU has anything to do with it, probably during that procedure you did something to trigger this 'error'. I take it your data is no longer accessible?
Your data should always be recoverable if you use a different RAID engine. Some recovery applications have a built-in RAID engine that can simulate various RAID-levels.
There are some important things you should know:
- how many drives and in what order were they used
- what was the stripesize used
The first question is probably: can u still see/detect all RAID0 disks?
