TITLE: Windows 2000 Fix for Hard Disk Performance After Suspend-Resume (Q817472)

VERSION: 1.00 Rev C
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). 

This hotfix replaces hotfixes 813908, 323153, 314695, 305176, 305098, 304912, 
304572, and 298505.
