Installed a new motherboard/processor - now how do I access data on my existing RAID 0 array?

My computer had a pair of SATA drives that were setup as a RAID 0 array using the Intel Southbridge controller on the motherboard.  They were the boot drive (XP Pro) and it worked great.  The motherboard got zapped by a static shock and died.  I purchased a new motherboard/processor (ECS RS400-A) with an ATI chipset that uses the Silicon Image SATA controller.  When I intsalled the new motherboard I wanted to use the same drives.  I installed them, set the BIOS to enable the array, and the hardware recognized the drives and the RAID 0 array but the computer would not boot from them.  I have since installed a new IDE drive, loaded XP Pro and now I just want to get the data that is on the SATA RAID 0 array.  When I use the Disk Management tool under XP, it recognized the array as one drive and I was able to assign a drive letter but XP says the drive is not formatted and has no file system (I know it is formatted to NTFS).  Now it is asking me if I want to format the drive!  Anyone know how to get at the data on the array???

That option is not offered in the "Disk Management" part of the "Computer Management" tool.  Under status is says "Healthy (Active)" but under File System it is blank.

Commented:
Since the RAID controllers are from different manufacturers, you will not be able to recover the data on the array.  The low cost SATA RAID controllers use proprietary RAID algorithms that don't adhere to standard RAID conventions for parity and split computations.

A good article at the LinuxMafia web site on this is here (it is for Linux but describes SATA RAID controllers and "fake raid"):

STOP !!!   Do not do anything to those drives -- #1 rule of data recovery !!

Download RAID Reconstructor from www.runtime.org

The free demo will show you what it can recover (probably everything in your case unless you've written to the drives).   You'll have to buy a license to actually recover the data ($99).

If your lucky you might be able to recover the data by using the software mentioned by gary. But, never save any data of any importance on a raid 0 array. Raid 0 has no redundancy, and the fact that it uses one more drive than usual increases the possibility of this data getting lost due to a bad HD or some other malfunction. I also wouldn't use raid 0 for the OS. What raid 0 is usefull for is to store temporary data, particularly for video editing, but once edited it should immediately be moved to a safe place for storage, or if you want to risk using raid 0 for storage it is essential to rune backups at all times.
