hi - i dont have tons of linux experience. my in-depth unix experience was many years ago. im building a system containing: - abit ic7g motherboard - 2 wd 160gb sata hard drives - red hat linux workstation version 3 the drives have been physically installed and the bios configured to run the disks as a raid (either raid0 or raid1). this is verified during the post. when i try to install linux, the disk partitioning program reports two disks /dev/sda & /dev/sdb individually with 160gb capacities available for partitioning, not one. whether using bios raid0 or raid1, only 1 disk should be available (with 160 or 320 gb available, depending on the raid flavor). whats wrong? bob singer - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
