raid 0 "error occured"

[George]

What is this ?
I run chkdsk and found no problem. I marked the disk as normal using Intel
storage manager and it runs fine.
Still I worry.
Any suggestions?
Thanks

If the drives in the array are not designed for RAID use it could be a
timing error. RAID relies on very exact timing of read/writes. Many consumer
drives can't meet these requirements. When this happens you will see errors
from the controller. This can be exacerbated by the fact that the Intel
onboard RAID chips don't have their own CPU. They use the computer's CPU to
do a lot of the work. If you are running a program that maxes the CPU and
you have drives not designed for RAID you will see these errors on a regular
basis. Eventually the controller will think the array has a bad drive and
take one of the drives offline. When this happens you may lose all the data
on the array. At the very least this error is a warning that something is
wrong and need further investigation.
