I understand that you have an older motherboard that failed with your information on RAID.
Before we proceed, when having information that is sensitive and priceless you don't use a RAID 0 as this kind of RAID will not give you nay data protection. I personally will recommend you to use RAID 1 where if your motherboard or one hard drive fails, you can move the hard drive in to another computer and recover the data.
Now, currently you can use any newer motherboard that supports RAID to try to recover the information.
If the RAID status is failed then I recommend you to contact a data recovery software developer to determine if the information can be recovered.
I was able to move my 2 RAID 0 drives from my DELL 9200 using Intel® Matrix Storage Technology to my new Intel motherboard DZ68BC as a D: RAID 0 drive. I use another drive to boot from and hold the OS. The Intel raid software on my new system (now named Intel Rapid Storage Technology) detected the 2 disks automaticly.
Many thanks for all the information, although since then I have acquired another 865perl MB online, and everything is now okay. I have trusted raid's of all types at work for many years, and knew I was taking a bit of a risk with raid 0, but started out with it at a time when large drives were not so affaordable as they are now. I would have had the same dilemma, in this case, with a raid 1 or 5, since it was the MB that failed. Since that is no longer an issue, I will file your responses for future reference, but for now, I have decided to simply duplicate all important files on other drives, rather than use raid technology. It seems the easiest way to eliminate concerns about compatibility.
