RAID Debacle...need help real bad
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 get 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 gives me the same message and does not see the drives.
When using Acronis TI 11 in windows mode when I try to backup from the RAID drives I get a 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?

I'll let someone else with more disk knowledge chime in, but I'm going to hazard a guess and say that only zero-filling the drives is going to remove the signature that the PCI-E controller left.
I'm not sure what you mean by "initialize." I created the array and then used two ntfs partitions and they are seen in windows if I boot off a single drive.
