SMARTMON.EXE Does Not Report Cache Information (127143)
The information in this article applies to:
• Microsoft Windows for Workgroups 3.11
• Microsoft MS-DOS operating system 6.0
• Microsoft MS-DOS operating system 6.2
• Microsoft MS-DOS operating system 6.21
• Microsoft MS-DOS operating system 6.22

SYMPTOMS
When you are running the SMARTDrive Monitor tool (SMARTMON.EXE) that is
shipped with Microsoft MS-DOS version 6.0 or higher, the tool does not
report any caching information for SMARTDRV.EXE even though SMARTDRV.EXE
is loaded properly.
CAUSE
The SMARTDrive Monitor tool does not show SMARTDrive caching information
for the following types of drives:
• Drives that are not cached.
• Network drives.
• CD-ROM drives.
• Hard disks running in Windows for Workgroups version 3.11 with
32-bit file access enabled.
MORE INFORMATION
Drives That Are Not Cached
SMARTMON.EXE cannot report cache information for a drive if caching for
that drive has been disabled.
Network Drives
SMARTDrive does not cache network drives, so SMARTMON.EXE cannot report
cache information for these drives.
CD-ROM Drives
SMARTMON.EXE version 1.03 does not recognize the caching of CD-ROM drives
because it was not designed to do so. SMARTMON.EXE 1.03 was originally
released with Microsoft MS-DOS version 6.0, which includes SMARTDrive
version 4.0. SMARTDrive version 4.0 does not cache CD-ROM drives.
Hard Disks Using 32-Bit File Access
The 32-bit file access feature in Windows for Workgroups 3.11 uses a 32-bit
protect-mode cache (VCACHE.386) that replaces SMARTDRV.EXE at the Windows
level. When you use the 32-bit file access feature, SMARTDRV.EXE caches
only floppy and CD-ROM drives. SMARTMON.EXE does not report caching
information for hard disks using the 32-bit file access feature because
VCACHE.386 has disabled the hard disk caching in SMARTDRV.EXE.
The only way to work around this behavior is to not use the 32-bit file
access feature in Windows for Workgroups 3.11. You may not want to disable
the 32-bit file access feature, however, because doing so causes you to
lose the performance increases that 32-bit file access and VCACHE.386
provide over SMARTDrive's real-mode caching.
