Hi. Thanks. I'm not sure what I am going to do. I can't believe that
these drives are that bad, but all four drives are reacting the same
way. So it's either the machine or the drives. My hunch is it is the
drives since I've used this same machine successfully with other
drives. 

I guess I'm dreading that I'll probably have to pull the drives and try
them in another machine.
