Hi,
I have used AVR DOS with SD card and that worked fine. Now I am trying it with a harddisk. But I allways get error 227 when I do the Driveinit(). I have cheked the hardware a dozen times and it is how it should be. I also tryed it with the reset and CS2 connected (or tyed to VCC or GND) . Strangly if I set the Ata_reset_connected to 1 it hangs itself altogether. I tryed with mega644 and mega32. I eaven tryed several jumper settings of the HDD (and yes it is FAT32 and the Dfilesystemstatusfat is set).
I have tryed everything possible.
Does anyone have a schematic and code that works and has been actually tested?
I am really getting anxous, have been trying since a week but it just wouldn't stop showing that ****** error 227.

Hi,
thanks for the reply.
I have been working with SD card again just to test. It is absolutely awfull. The system seems to work and not work totaly random. Sometimes it works, then without changeing anything it doesn't work. It is totaly unstable. I think I will chuck everything away and get a new job as a road sweeper. I have no idea what is going on here, perhaps I have a brain tumor. I can't drink so much as I want to puke.
