For more information about this issue, refer to Microsoft Knowledge Base Article 817472, "IDE ATA and ATAPI disks use PIO mode after multiple time-out or CRC errors occur."
Provides a fix to prevent an issue where the primary IDE channel transfer mode setting changes from high speed mode (DMA mode) to the lowest speed mode (PIO mode) after the notebook has been suspended and resumed multiple times.
