DOCUMENT:Q127143 09-OCT-1999 [win3x] TITLE :SMARTMON.EXE Does Not Report Cache Information PRODUCT :Microsoft Windows 3.x Retail Product PROD/VER:MS-DOS:6.0,6.2,6.21,6.22; WINDOWS:3.11 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows for Workgroups version 3.11 - Microsoft MS-DOS operating system versions 6.0, 6.2, 6.21, 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.
