Some hard drives don't work well with RAID. What happens is a timing
problem. In a RAID array the controller is trying to queue the read/writes
for the most efficient movement of the heads. This means the drives may get
a burst of commands that they can't deal with before the controller is
expecting a response. The controller thinks there is an error and logs it.
After so many errors the controller fails one of the drives and removes it
from the array. This is sometimes a combination of the controller, CPU, and
hard drives. Most onboard RAID controllers don't have a dedicated CPU but
use the computers CPU do the RAID calculations. If you combine drives that
aren't designed for RAID with a marginal CPU and an onboard controller you
will have many problems. What is the exact model number of the drives? What
are your system specifications?
