The disk in question is a
FUJITSU MPC3043AT/6018 using ATA/ATAPI rev 3 according to atacontrol.
It is master on its controller and uses UDMA33 transfers, and has an idle 
PIO4 cd-rom player as a slave.

The controller is identified in dmesg as:
atapci0: <VIA 82C586 ATA33 controller> port 0xe000-0xe00f at device 7.1 on 
pci0

Thank you - I will check that.

I might try turning DMA off to see if that helps...
