The driver will retry the operation a few - times. Should the retries fail, it will switch from DMA to - the slower PIO mode of communication with the device. - - The problem can be caused by many factors, although - perhaps the most common cause is faulty or incorrect - cabling. Check that the ATA cables are undamaged and rated - for the Ultra DMA mode in use. If you are using - removable drive trays, they must also be compatible. Be - sure that all connections are making good contact. Problems - have also been noticed when an old drive is installed on the - same ATA channel as an Ultra DMA 66 (or faster) - drive. Lastly, these errors can indicate that the drive is - failing. Most drive vendors provide testing software for - their drives, so test your drive, and, if necessary, back up - your data and replace it. - - The &man.atacontrol.8; utility can be used to show and - select the DMA or PIO modes used for each ATA device.
