The information in this article applies to:

Microsoft Windows for Workgroups version 3.11

SUMMARY

Windows for Workgroups version 3.11 caches disk writes by default when the 32-bit file system is enabled. This includes MS-DOS DoubleSpace 6.2 volumes; however, it does not include third-party disk-compression systems.

MORE INFORMATION

To disable write caching with the 32-bit file system, add the following line to the [386Enh] section of the SYSTEM.INI file:

   ForceLazyOff=<drivelist>

where <drivelist> is the list of drives in which you want to disable write caching. (Do not use any delimiters or spaces.) For example, the line

     ForceLazyOff=CDF

would disable write caching on drives C, D, and F.
