Description (Beschreibung):

The Win32_PerfFormattedData_PerfDisk_PhysicalDisk "cooked" data performance counter class represents counters that monitor hard or fixed disk drives on a computer. Disks are used to store file, program, and paging data and are read to retrieve these items, and written to record changes to them. The values of physical disk counters are sums of the values of the logical disks (or partitions) into which they are divided. This class is shown as the Physical Disk object in System Monitor. The WMI source of its data is the high-performance Cooked Counter Provider. This class derives its raw data from the corresponding raw class Win32_PerfRawData_PerfDisk_PhysicalDisk. The original data source is the PerfDisk performance library. This class was added for Windows XP.
