Have a vista system with a raid 1 running says the the raid was made and
running fine but the the other drive dose not show on desk top

Drives do not show up on your desktop unless you place a shortcut there...
you can do so from Windows explorer
 
The other drive should not show.

In RAID 1, the first drive is your main drive and the second one is more
like your "ghost twin of first drive". The ghost drive will only appear when
something goes wrong.

You need to google "raid 1". Hopefully, you will understand that your
second drive is
mirroring your first drive and so you should not see second drive icon
on your desktop.

No more later,

One has to wonder why, if he doesn't realize this, he is running RAID1
at all.

Wow1, perhaps you could explain why you're using RAID1 and what you
hope to gain by it. With very rare exceptions, RAID1 is not
appropriate for home users.
 
As I was told google fans 0 is Redundant and 1 is Performance


Sorry, that's not correct. You have it backward. RAID 1 (mirroring)
uses two or more drives, each a duplicate of the others, to provide
redundancy, not backup. It's used in situations (almost always within
corporations, not in homes) where any downtown can't be tolerated,
because the way it works is that if one drive fails the other takes
over seamlessly. Although some people thing of RAID 1 as a backup
technique, that is *not* what it is, since it's subject to
simultaneous loss of the original and the mirror to many of the most
common dangers threatening your data--severe power glitches, nearby
lightning strikes, virus attacks, theft of the computer, etc. Most
companies that use RAID 1 also have a strong external backup plan in
place.

RAID 0 (striping) in theory provides improved performance, but in
practice, the improvement is usually tiny, and the increased risk to
your data makes it dangerous.

RAID, of any kind, is very likely inappropriate for you.

Does that happen so seamlessly that the user is not even
aware of the failure, or is there an alert posted that one
drive has failed?

Thanks.

The driver software may provide a way to alert you, depends on the RAID
controller. Of the cheapo IDE ones I've used in the past, the IT8212 has
an email facility but you must be logged into a console to run the
monitor I think as last one that failed on me didn't send me any mail.

May help in video encoding where long streams of data are read or
written. Large streams of data are the only part that RAID 0 will
improve and that's not helped by a fragmented drive in any case as seek
times will be typically longer than for a single drive.

+ if 1 drive fails, the data on the other good drive(s) is only
partially there and no good to man or beast.

I have very little personal experience with this, so take what I say
with a grain of salt. My assumption is that there has to be some form
of alert. If a drive failed, it would need to replaced, or else you
wouldn't have the redundancy you thought you had. So you'd have to be
alerted of a failure.

Correct. That's exactly why I said "the increased risk to your data
makes it dangerous."
