degraded raid mirror

[skytopdesigns]

i just had my vista computer set up with 2HD raid set up.

i have 2 nvidea cards

this is the second time that when i boot. it starts fine but then shortly
after it shuts down and restarts and flashes in red "degrated nvidea mirror"

then it seems to be fine
what does that mean?

thanks
Lisa

Hi,

You may have a failing drive, or just need to rebuild the array. Some links:

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?

the 2 raid drives are brand new.

So possible to have a failing drive then, just because they are new
doesn't mean they are necessarily immune from failing (also known as
"bathtub curve").

i understand that new dosnt mean immunity from failure. i just had a 1 year
old drive go on me

my computer guy suggested a rebuild

i hit f10

but when i hit rebuild, nothing happens
