This is a program that attempts to identify the
presence of a write-caching disk controller.

Such a controller jeopardizes SQL Server data
integrity.  CACHETST only detects write caching
software or hardware.  The FAT disk cache does
not do write caching, and is not detected.

The program is very simple, and requires no
parameters.  It is an OS/2-only program, and
should be run on the server.  

In a few seconds, it will print out data
that should allow you to determine whether your
SQL Server hardware platform has a write-caching
disk controller.
