Best answer as chosen by user don49-don: Sorry but this one can not be answered. Why?
There are too many RAID systems out there. I can't guess if this is a hardware raid that works without drivers or if it's one that we have to load drivers to access as well as install.
There are too many reasons for this to fail that the best place to check is the documents about the RAID that came with the machine.
But fair warning. Some of those home or shop built systems set up RAID and never tell folk how they did that or how to re-install.
