| This package contains a fix for the following Windows XP issue that could occur on the listed desktop models.
After a desktop cycles through Suspend and Resume modes several times, hard disk performance may be reduced. If Device Manager is used to view the properties of the IDE channel to which the drive is connected, the Advanced Settings tab may show that the current transfer mode for the drive is "PIO Mode."
After the Windows IDE/ATAPI Port driver (Atapi.sys) receives a cumulative total of six time-out or cyclical redundancy check (CRC) errors, the driver reduces the communications speed (the transfer mode) from the highest Direct Memory Access (DMA) mode to lower DMA modes, in steps. If the driver continues to receive time-out or CRC errors, the driver eventually reduces the transfer mode to the slowest mode (PIO mode).
For further information, refer to Microsoft Knowledge Base article 817472, "IDE ATA and ATAPI Disks Use P10 Mode After Multiple Time-Out or CRC Error Occur."
