The information in this article applies to:

- Microsoft MS-DOS operating system versions 6.0, 6.2, 6.22 
-------------------------------------------------------------------------------

SUMMARY
=======

The SMARTDrive Monitor (SMARTMON.EXE) provides an interface to the performance
of MS-DOS 6.0 and 6.2 SMARTDrive 4.1 and MS-DOS 6.22 SMARTDrive 6.22 SMARTDrive
5.01.

SMARTDrive Monitor may not work correctly with disk-compression software such as
DoubleSpace or Stacker.

MORE INFORMATION
================

Using SMARTDrive Monitor with DoubleSpace
-----------------------------------------

If you try to turn on caching for a DoubleSpace-compressed drive by typing the
SMARTDRV.EXE command at the MS-DOS command prompt, you receive an error message
indicating that you must specify the host drive rather than the compressed
drive.

However, if you are using the SMARTDrive Monitor and you select the compressed
drive and then select the Cache Reads And Writes button, this action is ignored
and you do not receive an error message. When SMARTDrive Monitor is reloaded, it
defaults to no read or write cache on the DoubleSpace-compressed drive.

Using SMARTDrive Monitor with Stacker
-------------------------------------

SMARTDrive Monitor defaults to drive C. If you have installed Stacker and you are
swapping drives, SMARTDrive Monitor reports zero cache hits on drive C. To use
SMARTDrive Monitor with Stacker, select your host drive.

Microsoft has confirmed this to be a problem in SMARTDrive Monitor version 3.1.
We are researching this problem and will post new information here in the
Microsoft Knowledge Base as it becomes available.
