Umm... fdisk shows that /dev/hda has 255 heads and /dev/hdd has 16 heads. That explains the cylinder difference. The BIOS says they both have 16 heads. There is no BIOS update to the Shuttle SK41G. I don't know if this is a linux bug or a BIOS bug. To me the BIOS looks right. -eric wood Eric Wood wrote: > Install RH9 and I want to RAID /dev/hda and /dev/hdd together.
