I notice all 3 problem drives are listed as dynamic. Can you give some info on why you have them setup as dynamic?
Did you have them setup to have 1 drive letter span all 3 drives?
It's unlikely that all 3 drives died at the same time while your primary drive is fine. It is possible that 1 drive has a problem and that has broken your dynamic (RAID) setup.
Are all 3 drives SATA? Are they all on the same controller? Does your controller offer RAID abilities that you are using. (Although it appears you were using windows to do software RAID, most likely)
Is this a system that has been working and then the drives stopped showing up or is the boot drive just recently being setup and you are trying to carry over the 3 drives from a previous setup?
I assume you are running XP Pro.
