# My system is complaining that I do not have a UDMA-66 compliant cable
# attaching my hard drive to the mother board. I am in fact using such a
# cable, and I have already purchased another cable and tried it just to
# check that the fault was not in the cable. The excat error message is
# from the kernel is :
#
# ata0-master: DMA limited to UDMA33, non-ATA66 compliant cable

# ata0-master: DMA limited to UDMA33, non-ATA66 compliant cable
# ad0: 9765MB <Maxtor 91024U4> [19841/16/63] at ata0-master UDMA33
# ad2: 3060MB <Maxtor 83201A6> [6218/16/63] at ata1-master WDMA2
# afd0: 96MB <IOMEGA ZIP 100 ATAPI> [96/64/32] at ata0-slave using PIO0
# acd0: CDROM <ASUS CD-S500/A> at ata1-slave using PIO4

Are both Maxtor drives on the same channel? Wild guess, but it might be
that the older Maxtor drive could be causing the entire channel to kick
down to ATA/33. <shrug>
