Migrating RAID5 from old computer build to new computer build

I had an older computer with a Asus M2n Sli Deluxe MB running a RAID5 (made up of 3, 500 WD HDs) from the MB controller; I believe it is a JMicron software controller.

The Motherboard kicked the cyber bucket. It's dead, I tried a new power supply, a new CPU and it just starts and than turns off. It doesn't even boot. Nothing.
So I purchased a new mother board: Asus A88X-Pro, new CPU: AMD A10 5800K, and Ram: Viper 8gb 1stick.

I've installed most of my old components: Bluray writer, DVD writer, Nvidia 550 Ti card, a 120gb SSD, and my 3x500gb HDs in RAID5. Some of my old components had IDE strips that couldn't be used any more( 2 dvd writers, a Floppy with USB 2.0 card reader, and a 1394 case connection) because there was no IDE connection on the new MB and I just figured I'd leave out some things and streamline my system.

Problem:
How can I migrate my old RAID5 to this new system without losing the files I had on there? The new MB does NOT recognize the drives as a single RAID5. It only shows 3 500 WD HD's in the bios. I tried setting the SATA connections as RAID but the setting sets all the SATAs to RAID and if I press Ctlr R at boot up, the boot menu askes me to "initialize" the drives, this would mean wiping the drives and creating a new array and I do NOT want to do that because i would loose all my files.

What can I do? Is there a way make the new MB recognize my old RAID5? Or, is there a RAID5 Controller card I could purchase that would recognize my old RAID5?

Any help would be appreciated. Thank you

If as you believe - it's JMicron
Then this should work

It's a JMicron RAID

I would suggest using raid recovery to migrate your data off the array and then use the motherbds chipset raid controller to create a new array and migrate your data bac in, this leaves you with a backup of you data (what you migrated to from the old array)

Forgive my naïveté, but how would I do that?

So I got the card today and plugged it in. The computer recognizes the 3 drives as 1 drive, however it can't read the drives. if I try to access the drive, it asks me to format the drives.

AM I doing something wrong? I have the card set to raid 5.

I did a little more investigating and I found that the raid controller chip on the card is a "JMB 393". I went and looked at my old mother the board and sure enough there was a raid controller chip on there but it's labeled, "JMB 363"

I did a google shopping search for JMicron 363 controller card and found a few.

So I am considering purchasing the JMB 363 raid card.

Do you think it will make a difference? Should a JMB 393" card be able to read a "JMB 363" created raid 5? Or does it make sense that a "393" card would not be able to read a "363" array?

Do not initial or format the volume
Base on your post: JMB393 is a 2x ports
http://www.jmicron.com/JMB363.html
JMB363 is not a RAID5 card.. So i guess your RAID is not created by this chip! but rather the MB RAID engine...
What was the old MB model?

The MB was a Asus M2n Sli-Deluxe

Your RAID is created by - NVIDIA MediaShield™ RAID supports RAID 0, 1, 0+1, 5 and JBOD span cross Serial ATA drives
not JMicron... To get your data you can just get ANY MB with - NVIDIA MediaShield™ RAID

Thanks, I'll give that a try and let you know how it goes.

Thank you to everyone who replied and helped with this problem. You were all very helpful.

I did find a solution. Here is what I did:

I decided to try a software recovery tool from lc-tech called File Recovery Professional.

I plugged my old hard drives in to my new motherboard in the same sequential order I had them in when I created the RAID5 on my old motherboard. I downloaded the software. Ran it and selected RAID Reconstructor. Next, I contacted lc-tech's tech support via live chat and they were very helpful explaining how to use the software properly. I had to run a series of scans on the drives to find the right possible combination to read the RAID array. It took about an hour and a half but I finally found the right combination and recovered ALL OF MY DATA!!! I then transfered the data to an external hard drive as a back up. After I trippled checked that I had all my files back, I powered down, disconnected the drives from the motherboard and than plugged them into the RAID card as suggested by FireWire2 and wipped the drives and created a new RAID5 array and coppied the files to the new RAID drive.

I will give a brief description below but

***beware*** you can get the combination close and find parts of your files. Make sure to double check that the files you find work after you save them to a new external drive. I found a few combinations that were close and the results showed all most all the my missing data, however when I saved the files to another drive and tried to listen to music files they sounded like skipping records or cds. When I went to open picture files they looked stripped and some only had the Green and Blue data but not Red and vice versa. SO double check before you reparation and intialize your old drives***

To help other's who may have this probelm; here are the parameters I used to read the motherboard Nvidia MediaShield created RAID5 array:

set the RAID to: RAID5 Generic HW
# of Drives I had 3 (but this can be different depending how many drives you use to create the array)
Location of the drives from the drop down menu
Set all drives to start at sector "0"
Drive order: 1-2-3 (the order depends on the order the drives were written to from the software and can easily be rearranged)
Stripe Size: 128
Parity Rotation: backwarddyn

after I plugged these parameters in, the software read the array correctly and I found all my files.

if you need help feel free to dro a message here and I'll answer as soon as I can.
