When FastATA goes wrong - how best to recover?

[paul1981]

This sounds odd. What partitions do you have on your CF drive? What brand is the CF drive? Without ata3.driver running the FastATA should act as a normal A600/A1200 IDE port. Maybe it isn't doing with your particular CF card... that's all I can think of at the moment.

Is it possible that the PIO settings are stored in hardware on the FastATA?

No, they're stored in the prefs file ENVARC:ATA3.Prefs
Maybe PIO3 is the maximum speed for your CF card? I'd settle for that, I don't think you have any hardware problems. Weird though how you did a reboot at the time and it was still NDOS. Was it NDOS from a cold boot?
