TITLE: Windows 2000 Fix for Reduced Hard Disk Performance After Frequent Suspend/Resume VERSION: 1.00 Rev A DESCRIPTION: This contains a fix for the following Windows 2000 problem that could occur on the desktop models listed below. After you suspend and resume your computer several times, hard disk performance may be reduced. If you use Device Manager 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.
