Winmsd.exe May Show Invalid Drive Statistics in Reports

ID: Q167001

The information in this article applies to:

Microsoft Windows NT Workstation version 4.0
Microsoft Windows NT Server version 4.0

SYMPTOMS

The Windows NT Diagnostics utility, Winmsd.exe, may show invalid drive statistics in a saved or printed report. This can occur for drives where the product of bytes per sector multiplied by sectors per cluster is smaller than 1,024.

CAUSE

When generating a report, the Winmsd.exe diagnostic utility shows drive statistics in kilobytes and not in bytes, as it does on the Drives tab. When calculating the total and free disk space of a drive, it uses the following formula:

((bytes per sector * sectors per cluster) / 1024)

If the product of bytes per sector and sectors per cluster is smaller than 1,024, the result equals 0, and the drives report will show 0 KB as both total and free disk space. This may happen with small NTFS partitions where bytes per sector equals 512 and sectors per cluster equals 1. However, the Drives tab does display the correct statistics.

STATUS

Microsoft has confirmed this to be a problem in Windows NT version 4.0. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
