For some windows machine, I am getting error while trying to fetch performance category for logical disk, but for some window machine I am not getting this error.

Why this error appears for some window machines?

var processorCategory = PerformanceCounterCategory.GetCategories().FirstOrDefault(cat => cat.CategoryName == "LogicalDisk");

message error :

System.ArgumentException: Invalid value '' for parameter 'categoryName'.
