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.
