Thanks for the tip, it look like when I get it working I can tune it a
little better, but unfortunately I get the same errors using hdparm. Using
hdparm I have tried all UDMA modes and still get the CRC error. With any
mdma mode I get "timed out waiting for DMA". PIO is all that works. Any
other ideas?
Thanks - Ralph
