In the BIOS I turn DMA off for /dev/hda and /dev/hdc, but they still show up in /proc/ide/.../settings as using_dma 1.

Thanks for all the replies concerning this.
I have bought an off-the-shelf 24" round ATA 133 IDE cable, and installed that in place of the 40-wire cable.

Kind Regards,
Keith Roberts
