Thanks! I just tried this on a system as close to the one you have as possible here in the lab with this result: atapci3: port 0xa800-0xa807,0xa400-0xa403,0xa000-0xa007,0x9c00-0x9c03,0x9800-0x980f mem 0xfdfff000-0xfdfff3ff irq 16 at device 13.0 on pci1 ata6: on atapci3 ata7: on atapci3 ata8: on atapci3 ata9: on atapci3 ... ad1: 78533MB at ata8-master SATA150 devel# dd if=/dev/ad1 of=/dev/null bs=1m count=200 200+0 records in 200+0 records out 209715200 bytes transferred in 3.470972 secs (60419732 bytes/sec) devel# dd if=/dev/zero of=/dev/ad1 bs=1m count=200 200+0 records in 200+0 records out 209715200 bytes transferred in 3.513703 secs (59684956 bytes/sec) That makes me *seriously* doubt that ATA is at fault here... -Søren
