Please turn on the "Write sensor result to disk" option within the sensor settings, and check the results. The query should look like this:

SELECT Name,PercentDiskReadTime,Timestamp_Perftime,Frequency_PerfTime,PercentDiskReadTime_Base FROM win32_perfrawdata_perfdisk_physicaldisk WHERE Name LIKE '2 P:'
