Moving a RAID 0 to a different board with same raid mfg

Currently my mother board is a MSI K8N Neo4 Platinum/SLI nforce Socket 939 Motherboard
Heres the link to the board info

and baord i want to move it to is a Asus A8N SLI Premium nForce4 socket 939 Motherboard

Now my question is i want to move my RAID with out destroying any of the data.the mfg of the raid chip is silicon and on on both of the boards but hwo would i manage to get the raid up and running once i attached it to new board? is it possible to just plug and play or is there some critical steps to follow.
i have 2x300gig hd's and am pretty worried about the data being erased, its prety sensitive.

i have tried moving raid before but from different mfg chip's but never tried moving to same one's but diff boards.

No, you can't move a RAID-0 array that uses a chip on the motherboard.  Information about the array is stored on the motherboard, which would be lost if you changed motherboards.  If you had a controller card, then you could move the card and the array.

Not the solution you were looking for? Getting a personalized solution is easy.

This is VERY simply solved by putting another HDD on the secondary IDE controller, and copying all data from the RAID to that drive.  Take out the single IDE, move it to the ASUS, and if you MUSt use RAID 0 (why are you doing this?, why not use RAID mirroring, it is much safer), then copy all that data to the new RAID array that you decide is best in the ASUS.  Hopefully you might consider RAID 1, supposed better speed of RAID 0 is not worth this kind of hassle that you get, which you wouldnt have with RAID 1.


its SATA drive's btw.thats a bummer if i can't move the raid,so far ASUS bench's are killin MSI and im geting a really good deal on it as well.but why would the board store the info? shouldn't the silicon chip hold the information and when i move the raid to new system could i not tell silicon settings to rebuild raid?
you can try moving the drives over and creating a raid 0 on them and bypass and formatting or intialization and it may work but one other issue your going to run into is if your os is on that raid it is not going to like swapping motherboards and your going to most likely have to reinstall the os anyway or spend hours fighting it to get it boot and it still wont work properly. I suggest just backing up your data and reinstalling, and in the end it will save you time and asprin. Also were your data is sensitive and you can afford loosing it and your running a raid 0 backup every day, your more likly to lose data running a raid 0 versus a single hdd, if the data is that important switch to a raid 1.


well its just archive of stuff, i got my OS on a seperate 80gig ide hd.but since the controller chip will be from same mfg i don't think it should really matter,maybe gota update the settings but i want ot be 100% sure before i attempt anything
First of all, BACKUP the data. That can't be avoided. Either by getting an external 300Gb drive, or burning to DVDs, it's something you should do regardless.

After that, if you set up your Raid settings in the new board exactly as the previous one, there's a chance it will be detected correctly.
Anyway, that's all you can do, and if it works, it works - if it doesn't you can't do anything about it anyway. So, there's really not much else you can do.

I'm kind of in the same situation, having 2 raid arrays (6HD's) on my MSI board - and don't even want to think about upgrading/replacing it. Currently looking into some sort of NAS system, so I can keep my data independently from my PCs.

The information is stored on the board because that's where the controller is.  The case exception is if you use the same controller in the target system, but I doubt Asus and MSI use the same configuration.  With an external controller card, you can replace them if the new controller card is the same or in the same family.


MSI = Silicon Image's SATARAID supports another 2 SATA II ports. Transfer rate is up to 300MB/s
ASUS = Silicon Image 3114R RAID controller 4x SATA with RAID0, 1, 10, 5

same chip maker BUT asus supports raid 5 and msi doesn't.but it really shouldn't make a difference right? i mean if you tell the silicon bio's to rebuild raid then it should magically build it?

it is kidn of expensive backing up 600gig's worth of stuff,hd's are geting cheaper but not cheap enough :p

I think those are not the same, if one supports RAID-5 and the other doesn't.  I also think you are asking for trouble putting 600GB of data on a RAID-0 and not having any backup.  It's an accident waiting to happen.


lol.its faster!!

anyone with any evidence about moving raid's or anyone whose done it before@??!
I agree, those are (most likely) different controllers.

Regarding the backups, that's why I chose 4x80Gb disks, so I could back it up easily into a 300Gb external HD.
If you're going to have 600gb without any backup plan, that's asking for trouble, BIG trouble. The bigger the disks, the more you'll lose.
There is no way to say if you can transfer the raid without losing data, even where they are different controllers its possible it may work, but its also possible it wont, I have seen raids fail when transfered between identical controllers and seen them work when transfered to a different one. The smart thing to do would be to back it up before you attempt it. I agree with every oneelse on your no backup solution with a raid 0 your inviting disaster, its not a question of if it going to fail but when, atleast with a raid 1 or 5 its has some redundancy if a drive fails or just falls offline, with a raid 0 if a drive fails or falls offline the data is gone and you will most likely need to spend thousands of dollars to recover it.
