Hi there,
i think your cf controller does not like the ide.device you are using.i mean the 4 way device (idefix.device),while the original (ide.device)found on the disk is "Compatible".
try to use the latest device and try other ide.device programs.
idefix,allegro , asimcdfs .all update the ide.device routines.
also do you have the latest "youride.device" version?
go to a cli,and run
version youride.device and report back the revision.
But you mate could really update your miggy .
why dont you get a 4091 scsi card or any other dma enabled scsi contoller.You will really explode the disk transfer.
consider the fastest solution.
