RAID Debacle...need help real bad

[Carrion21]

I have two 750gb WD drives and I used the onboard RAID to stripe them. A request came up asking if I wanted to clear the MBR and I chose, "No."

Then I installed Vista 32bit OS with no problems. I then tested the RAID performance using HD Tune and then made a backup of the primary partition using Acronis True Image 11 without any problems.

Then I installed a PCI-E RAID controller and plugged in my drives into it and then created a new RAID 0 array that the PCI-E RAID controller could see. I booted up without any problems and then tested the performance of the drives using HD Tune. The difference between onboard RAID and PCI-E RAID was slim, so I took out the PCI-E controller and returned it.

I hooked up my two drives back to the onboard RAID controller and it worked fine.

Now, when I went to make a backup using Acronis TI 11 using the recovery CD I and I got a quick error message, "dev/sda sil and nvidia formats discovered (using nvidia)," but

Acronis no longer sees my drives!!

I deleted the array and cleared the MBR and then created a new mirrored array and TI gave me the same message and still doesn't see the drives.

When using Acronis TI 11 in windows mode, I tried to backup the RAID partition and I got this message, "SCSI/host5/bus0/Target0/Lun0/disc" disk with major 8 minor 32 does not have a valid Intel Software Raid Signature."

How do I fix this problem?

you can use dban or wd diagnostic utility to write 0s to the drives , that will erase all raid information and you will be able to start over with clean drives.
