If you try reconstructing the array before you are sure you have resolved the original problem (be it BIOS setting, bad cables, dodgey controller or even a bad disk drive) then you risk compounding your problems and at least are likely to waste time. Sometimes people are in such a hurry to get access to their data that they cut corners to their detriment. I don't know if you are such a person, but I mentioned it anyway just in case. NeilBrown
