OK, if you have and ICH9 you *do not and can not* use the IIR driver, =20= the IIR driver is for HW based RAID cards from Intel (the devices show =20= up as CAM disks). I wonder where you got the impression that the IIR =20 driver was in use ? The ICHXX are all just plain (S)ATA devices, with =20= the versions ending in 'R' having a different PCI ID so the BIOS can =20 tell if you paid extra to get the software RAID "option" . Its all =20 just marketing rubbish...

I hate to bring this to you, but you will not have an intact =20 filesystem when the rebuild is done, you have no parity data to =20 rebuild from, just as the docs states. -S=F8ren
