Other than that, the output of dmesg is basically the same, but the devices were probed (?) twice: $ dmesg | grep -e ^ata -e ^ad -e ^acd atapci0: <Intel ICH2 UDMA100 controller> port 0xfc00-0xfc0f at device 31.1 on pci0 ata0: at 0x1f0 irq 14 on atapci0 ata0: [MPSAFE] ata1: at 0x170 irq 15 on atapci0 ata1: [MPSAFE] ad0: 29325MB <Maxtor 6E030L0> [59582/16/63] at ata0-master UDMA100 acd0: DVDROM <LITEON DVD-ROM LTD-165H> at ata0-slave PIO4 atapci0: <Intel ICH2 UDMA100 controller> port 0xfc00-0xfc0f at device 31.1 on pci0 ata0: at 0x1f0 irq 14 on atapci0 ata0: [MPSAFE] ata1: at 0x170 irq 15 on atapci0 ata1: [MPSAFE] ata0-slave: DMA limited to UDMA33, non-ATA66 cable or device ad0: 29325MB <Maxtor 6E030L0> [59582/16/63] at ata0-master UDMA100 acd0: DVDROM <LITEON DVD-ROM LTD-165H> at ata0-slave UDMA33 $ The LED is still on. The devices are jumpered properly in master-slave terms. I'll try to get a hold of another cable and see if splitting them across cables helps. Thanks a lot.
