First report after half of a day of experimenting.

Software RAID + S-ATA Drives + OS X = NO GO

I was able to create Apple raid in several configurations (all in stripping mode) but it all ends up with error while trying to fix GUID bootloader. If I use the Zephyroth’s method it gives me an "Device busy" error while trying “dd if=./guid/boot0 of=/dev/diskX bs=400 count=1” (“dd if=./guid/boot1h of=/dev/rdiskXsY bs=512 count=1” goes through correctly) and if I make only one partition (only RAID partition) than as gaz919 said I can’t access it at all. Luckily I have two 40GB Maxtor DiamondMax8 P-ATA (IDE) drives so I’ll try a RAID setup with those. The thing that I’ve noticed is nVidia RAID bios loses all RAID Array info as soon as I create Apple RAID, so just to be able to select the RAID as a boot device I have to recreate array info in RAID Bios (without clearing the data) and mark it as bootable. I’m not sure if by doing this I’m ruining something on the partitions since it won’t boot even by using DVD and rd=diskXsY combination.

I’m off to try the IDE RAID setup. Will report later.
