As it was already pointed, one disk is connected to AHCI-compatible controller. > ahci0 at pci0 dev 17 function 0 "ATI SBx00 SATA" rev 0x00: apic 4 int > 22 (irq 10), AHCI 1.1 > scsibus0 at ahci0: 32 targets > sd0 at scsibus0 targ 1 lun 0: <ATA, ST3750528AS, CC38> SCSI3 0/direct fixed > sd0: 715404MB, 512 bytes/sec, 1465149168 sec total This one, actually. > pciide0 at pci0 dev 20 function 1 "ATI SB700 IDE" rev 0x00: DMA, > channel 0 configured to compatibility, channel 1 configured to > compatibility > wd0 at pciide0 channel 0 drive 1: <ST3500418AS> > wd0: 16-sector PIO, LBA48, 476940MB, 976773168 sectors > wd0(pciide0:0:1): using PIO mode 4, DMA mode 2, Ultra-DMA mode 6 > wd1 at pciide0 channel 1 drive 0: <WDC WD2500AAJB-00J3A0> > wd1: 16-sector PIO, LBA48, 238475MB, 488397168 sectors > wd2 at pciide0 channel 1 drive 1: <WDC WD1600JB-00GVC0> > wd2: 16-sector PIO, LBA48, 152627MB, 312581808 sectors > wd1(pciide0:1:0): using PIO mode 4, DMA mode 2, Ultra-DMA mode 6 > wd2(pciide0:1:1): using PIO mode 4, DMA mode 2, Ultra-DMA mode 5 Those drives are connected to another, non-AHCI controller (or AHCI isn't supported on it). You can go in your BIOS and try to disable AHCI mode, boot normally, save a backup copy of /etc/fstab, edit current /etc/fstab, reboot, go in BIOS again and re-enable AHCI mode - as it should be faster and, sometimes, even more reliable.
