Having the dual-slot CF-IDE adapter AND a hard disk means you have 3 devices
there whether you plug something into the slot or not.
You'd get the same error if you had a 3-way IDE cable :)
Just move the CF adapter to a different cable, or the hard disk to a different
cable, and it'll be fine.

My PATA hard disk is crippled by CRC errors when it's on the same cable
as a 1GB SanDisk Ultra II CompactFlash card in CF to IDE adaptor. Any
ideas why?
By swapping around components, I've established that the problem is
unlikely due to the cable (which is 50cm long 80-wire), hard disk or
controller. When I swap to another, slower CF card (one that only
supports PIO rather than MWDMA), the error goes away and the hard disk
operates happily at UDMA/33.
No errors are reported for the CF card I/O.
The adaptor card is unbranded, model CF-IDE40 V.A1. It's a double-sided
type, but I'm only using one of the two CF sockets.
The spec sheet says
* Accord with: CF spec Ver2.0 and IDE/ATA-33 spec.
* Standard IDE interface: true-IDE mode, support DMA-33 transfer mode
I see the errors both with the old IDE code in 2.6.18 and with libata in
2.6.22
