- Can I place one of the SATA disks in another system (no ICH9R) and access the filesystems ?
A/ Yes, you will need to boot in to IDE mode, the RAID wont be able to recover but the information will be there. If you want to rebuild the array you will need another motherboard with the same RAID controller (ICH9R)
- Can I purchase a PCIe card with ICH9R so I can access the data ?
A/ You could but there are no RAID cards with the ICH9R
- I assume if I replace the motherboard, I'll have no issues. Is that correct ?
A/ Yes.You wont have any issues as you will be using the same RAID controller (ICH9R)
Out of curiosity, where does the ICH9R store the RAID configuration information ?
A/ On the hard drives. This is why you can use them in another system with the same RAID controller and they can work there.
