the like.

First, WHY do you want RAID? Do a bit of research and at least find out the
difference between RAID 0 and RAID 1 (the only modes applicable to 2 HDs)
before you go any further. You may find out it won't do what you want...

Then don't use RAID, keep the two drives seperate so when
video editing, you have one drive as the video source and
the other as destination... or if mixing tracks, these from
separate drives. Remember that RAID benchmarks well but
that doesn't translate directly to particular tasks.

I suggest an online tutorial, Google will find some. You
should not trust your data to only the amount of information
that participants in a usenet forum were willing to repeat
for the (n)th time... you'll end up getting the abbreviated
version of everything because the work to be through on our
part is greater than the work for you to do a web or usenet
search for the information.

Very true. If video editing with two drives, keeping them as seperate drives
is best. If you have four drives, then RAID-0 would be the way to go with
two arrays using one array as source and another as destination. Writing
back to a single drive or RAID array does not give anywhere near the
performance as two seperate drives/arrays. I would not reccomend any striped
array (raid-0) for storage of critical data.

First, look at the manual. Then, poke around in the bios. I'm a bit new to
raid myself, but just set up two different raid systems on 2 machines run
from the motherboards along with one on a high-end hardware (PCIe)
controller. Both required that the drives be enabled in the bios for raid
use, and then the raid array had to be configured in a separate raid
configuration utility that is tied to the motherboard's raid controller. To
enter that, you usually push some key combination F4, etc, after the bios
loads. The drives that you've enabled for raid use in the bios should then
appear in the raid utility able to be added to the raid array. You then
generally specify the type of array and which drives to include - within
that raid utility. Sometimes there is an option to make the array bootable.
...going back into the bios afterward, should show the new array as a single
bootable drive. You might then have to alter the boot order to make sure
that the array is in the right location in that boot order.

When loading the OS, Windows will ask almost immediately if you wish to load
3rd party scsi or raid controllers, and if so, hit F6. You have something
like 6 seconds to do so. If you miss that opportunity, you will have to wait
for a few minutes until windows reports that it can't find any drives.
...then start over and make sure you hit F6 quickly. You should have already
have created a driver disk onto a floppy using whatever procedure is
specified in your manual - usually simply running a utility on the MB driver
CD. From what I gather, Vista can load these drivers from something other
than a floppy, but XP and below still require the driver on a floppy.
Windows eventually prompts you to load the driver, and from at tpoint all
proceeds normally.

The above assumes that you are speaking about running the raid from the
motherboard rather than from the OS. ...you can't run a bootable raid from
the OS, however. Keep in mind that some boards support more than a single
raid system - I was confused about this on my asus board, that had both
silicon image and Nvidia raid controllers. I was attempting to load the
driver for the SI raid while I had configured the Nvidia raid. I'm not
positive, but I think that Gigabtye has a single raid system, but that only
some of the sata connections can be used for that raid setup.

After you have the machine running, most raid systems have yet another
utility that loads into the OS that provides information about the health of
the array. e.g., whether both drives are still functioning in a mirror, etc.
The higher end systems on hardware cards sometimes provide additional
features like email notification if any of the drives go bad (e.g., my
Adaptec PCIe hardware controller will perform this function, while some of
the motherboard based systems will not)
