I am also having this problem under FreeBSD 5.3. IDE RAID is HPT372 and SATA is Silicon Image 3114 dmesg shows: ad1: 19073MB <Maxtor 5T020H2/TAH71DP0> [38752/16/63] at ata0-slave UDMA100 acd0: CDRW <HL-DT-ST GCE-8160B/1.02> at ata1-master PIO4 ad4: 190782MB <WDC WD2000JD-00HBB0/08.02D08> [387621/16/63] at ata2-master SATA150 ad10: 190782MB <WDC WD2000JD-00HBB0/08.02D08> [387621/16/63] at ata5-master SATA150 ad12: 190782MB <WDC WD2000JB-00EVA0/15.05R15> [387621/16/63] at ata6-master UDMA100 ar0: ERROR - array broken ar0: 381564MB <ATA RAID0 array> [48642/255/63] status: BROKEN subdisks: disk0 READY on ad12 at ata6-master disk1 DOWN no device found for this disk First, the two SATAs are supposed to be a RAID0 array, but FreeBSD does not see them that way, so i have not played with any partitioning. ad12: 190782MB <WDC WD2000JB-00EVA0/15.05R15> [387621/16/63] at ata6-master UDMA100<< Thats one of the drives for the RAID, but the second drive is not showing up, what gives? The BIOS for the card can see it, but not FreeBSD. In FreeBSD 4.x, the IDE RAID works fine, but I cant get the SATA Raid to work. Its always that way, I can get one work, but not the other. I need an OS that can do both :( what was the command you useed to disable the DMA? I want to give that a shot to. I see that its sysctl, but what were the flags. Thanks, John Matthias F.
