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.
