DOCUMENT:Q141833 08-AUG-2001 [winnt] TITLE :Performance Monitor Reports Wrong Percent of Free Disk Space PRODUCT :Microsoft Windows NT PROD/VER:3.50 3.51 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Workstation versions 3.5, 3.51 - Microsoft Windows NT Server versions 3.5, 3.51 ------------------------------------------------------------------------------- SYMPTOMS ======== Performance Monitor reports the percent of free disk space incorrectly when used on a system with a different number of physical disks than the system where the workspace was originally created. Steps to Reproduce Problem -------------------------- 1. Go to a machine with one physical disk. 2. Using Performance Monitor, create a workspace in the alert log. 3. Add the counter %freespace to that log and make it <20% for drive 'C', parent '0'. 4. Save the workspace. 5. Load the saved workspace in Performance Monitor on a system with two or more physical drives. The % of disk space is reported as 0% instead of the correct value and the parent physical disk is reported as '--' instead of '0'. Performance monitor continues to generate event log entries at the specified interval reporting disk space at 0%. CAUSE ===== Performance monitor does not correctly translate workspace settings for disk space between two machines with a different number of physical disks. WORKAROUND ========== Create the workspace on each machine that has a different number of physical disks. Performance monitor will then report correct percent of free disk space for that system. STATUS ====== Microsoft has confirmed this to be a problem in Windows NT version 3.51. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
