i got two raptors in sata raid 0 mode.

I installed the drivers for the promise card, rebooted and build the raid setup via the utility.

i can see the raid listed as device connected to the pc via the controller card.

but can't see it in my computer screen.

how do i access it.

i know i have to format it first to access, but how can i format it, if i can't access it in the first place.

EDIT

I got my raid working, but benchmarks are horrible.

Am getting only 64 mb/s under sandra, where as it shows that average numbers of raid 0 mode for two 36 gigs raptors is 95 mb/s.

what is wrong with my setup. 🙁
 
Go to Control Panel > Administrative Tools > Computer Management > Storage > Disk Management and see if the array is listed as a disk.
 
So, the Promise RAID card knows the array is there, Windows knows the Promise RAID card is there, but for some reason the array is still not showing up.

😕

Is this one of the rigs linked in your signature, I presume?
 
Is there a chance you installed the drivers for a Promise IDE card versus a RAID card? I know with the Silicon Image chips, you can install drivers so it's just like a IDE card, or drivers that are for RAID. If you install the former, and have a RAID array, it won't see it in windows..

Are you sure the drivers are installed correctly in Windows? When you went to the Disk Management area like mechBgon suggested, did you scroll down? If the drivers are all installed, the RAID disk should show up there, and be listed as inactive IIRC.
 
Are you using the SATA on the DFI board, or a seperate SATA card? I just looked at all the LANParty NFII's and they all use the Silicon Image SATA chip...

You have this board right?

Onboard SATA/RAID: Sil3114 Serial ATA controller, 4x SATA, SATA RAID 0/1

am using off board pci controller, built by promise.

the onboard sata is for my sata drive.

my sata raid is on my promise sata raid controller.
 
Ahhh... I'm wondering if the system is getting confused because you have two SATA RAID Devices... Since the SI chip on your board is a four channel chip, may I ask why you are running a seperate card? The Promise and SI chips perform pretty much the same...in fact the SI usually has a slight edge from what I've seen.
 
Try moving your Promise card to different slots, dababus, and see if it gets any action that way. Or rebuild the array on your Silicon Image controller, it's got four ports and you can have a RAID0 alongside your existing SATA solo drive.
 
From what I have read, the onboard sata raid controller gets unstable at higher fsb. so people have opted for offboard sata raid cards.

am pushing fsb to 240 on my dfi mobo.

This is why i got a separate controller to begin with.
 
may be I should boot from my win 2k cd, load the drivers off the floppy for the card, and then access the hdd, format it with ntfs partition and then boot back to my system with my original win2k hdd.

do you guys believe that would work.

I can see the raid drives connected to the raid controller via the device manger. but not in windows.

may be they are not formatted in ntfs.

i can't think of any other reason besides that.

That is incorrect, unless there is an issue with the DFI itself. The onboard SATA controller is on the PCI bus, and on all NF2 boards, the PCI bus is locked @ 33mhz regardless of FSB. I would try it first...IMO.

I would seriously just try to use the SI first before you go through all that hassle.
 
well, i got my raid setup working on my promise card.

I ran sandra and only got 47 MB/S as compared to 95 MB/S for two 36 gigs raptors in Raid 0 mode. :|

what the hell is going on here.

am going to swtich to my onboard silicon image raid controller and bench again.
 
I got it setup on silicon image controller which is onboard and got a score of 83 mb/s

but if i attach my single sata hdd 80 gigs to onboard controller and set the controller in sata raid mode in bios,

i can't boot from my single sata drive.

i get an error message while loading my OS.

please someone explain me this raid setup.
 
i ran sandra benches again under win xp for my raid setup working off my onboard silicon image controller.

i got 64 mb/s now. what the hell is wrong with my raid setup.

am using two raptors 36 gigs.

sandra reports average score of 95 mb/s for two 36 gigs raptor in raid 0 mode.

why am I getting such a low score.

somebody help me.
