From a machine's dmesg: ad0: 38166MB <ST340016A> [77545/16/63] at ata0-master UDMA100 ad1: 12971MB <WDC WD136AA-35BAA0> [26354/16/63] at ata0-slave UDMA66 ata1-master: DMA limited to UDMA33, non-ATA66 compliant cable The cable IS compliant, but if I change the CD-ROM drive to a newer one, it's okay.
