If you change the partition type to something else, it really shouldn't autodetect any more.. Do you have an /etc/raidtab describing the array, and is raidstart being run at boottime by some script? In any case, mdadm --zero-superblock /dev/hda1 will zero the md/raid superblock on /dev/hda1 NeilBrown - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
