Raid 0 Question....

Okay, I set up a RAID 0 array on my RAID controller after the BIOS screen, and it comes up fine.

Question now is, when I install Windows, why does it show two drives? They are two identical drives... both on the same ID.

It says something like:

152626MB Disk 0 at ID 0 on Atapi [mbr]

There are two of these listed, both on the same ID and Disk #. Does this mean that Windows picked up the array? My understanding was that it would show up as one BIG drive, not two separate ones. I *did* use the RAID driver from the website to load up the Windows installation.

Also, are there some options in the BIOS that I'm missing that might be the culprit? I have a Chaintech 350ZNF or whatever, the one reviewed here and got the silver award.
 
I can't quite figure out where you are talking about in windows. Are you talking about the screen during the installation of windows where it asks you where to install to? If so then it's not showing two drives, it's showing two partitions (or a partition and some free space, etc). Some RAID controllers will take some space for themselves to keep information on, so it may be picking that up. Tough to tell since you don't list out everything it's reporting or even tell us the size of your drives...
 
Raid 0 or 1 _should_ only show up in the windows installer as a single drive. Windows shouldn't really "know" multiple drives are there.

If you're certain that you've created the array correctly (from within your raid controller's bios setup), perhaps you need to do the old F6 action during the install of windows..

You know, when you get that lovely blue screen (forshadowing, perhaps 😉, there's a message on the status line that says something like "Press F6 to load any additional SCSI drivers blah blah blah." You need to use a floppy (or perhaps a usb flash drive) to give windows the raid driver for your particular setup.
 
When I installed my Raptors in raid 0 , I had to enable 4 settings in the bios:1 enable the use of sata drives 2 for the controller (onboard),
3 for the raid,4 for the boot from...then Control+I(to access the raid config gui) to Set the array to 16kb stripe,and raid 0 , name the array, and finally, In win xp I had to hit F6 and install the drivers... then load partition hdd space / windows.

Hope this Helps

why did you pick a 16kb stripe size? i thought 128 was the best performing for most applications...

Because in the few tests i saw there was no real difference in time savings...top that off with i update little files all the time on my server (html code css etc) and it just seemed to make the best sense

hdd tach 8 mb

hdd tach 32 mb

does that answer your question?

I think I found the problem... I am not home yet and in front of my PC, but I think I loaded the wrong RAID driver and so it's not recognizing the array properly. Also, I'm going to fix some other hiccups there are as a result of my setup in the BIOS. I found a good guide in the motherboard section that I'm going to follow to the tee, else I'll just return the board and get something else, like the MSI.
 
I did that the first time as well on an asus p4p800-e deluxe i was loading the intel driver for the promise controller...it don't work😉

Did it list your drives at least, individually? Because that's what I'm getting now.
 
if its listing your drives individually then the there is something amiss..

did you list the boot drive as the array not a single drive?

is booting from the array possible and what needs to be done are in your manual

i'll look at the manual and get back to you

YOU got PM

also is it a znf3-250?

yes it did

sorry i read that all wrong ...after a cup of coffee the fog is lifting
 
As far as the stripe size question... the best stripe size will be based on your usage patterns...

you work mostly w/ LARGE files, select a larger stripe size, and vice versa.
