| Event Information | According to Microsoft: CAUSE: This problem occurs if you have installed one or more storage devices that do not support cache commands. The Windows 2000 SP4 Disk.sys driver writes many events to the system log when it performs write operations to a storage device that does not support cache commands. Some storage devices do not support cache control commands, such as the WRITE command when it is used with the ForceUnitAccess option or the MODE SELECT command that is used to change the cache. While Microsoft Windows 2000 Service Pack 3 (SP3) also logs events in the system log when it accesses a storage device that does not support cache commands, Windows 2000 SP3 writes these events only when it first accesses the device. However, Windows 2000 SP4 writes many warning events to the system log every time that it accesses the device that does not support cache commands. RESOLUTION: A supported hotfix is now available from Microsoft, but it is only intended to correct the problem that this article describes. Apply it only to systems that are experiencing this specific problem. You must restart your computer after you apply this hotfix. However, you do not have to restart your computer immediately after you install this hotfix. |
