SCCM 2012 - Free Disk Space report showing Empty

 

Wonder why the Free Disk Space has no data displayed in the Asset Intelligence - Hardware 01A report?

After some digging, found out it wasn't enabled by default in SCCM 2012.
To enable it, need to Go to Administration à Site Configuration à Client Setting à Default Client Settings (middle pane) à Properties

Under Default setting à Hardware Inventory à Set Classes.

Go under Logical Disk (SMS_LogicalDisk) à tick the column “Free Space (MB) à Press OK

Wait for sometimes for the hardware inventory cycle, then regenerate the report. The Free Disk Space data will be populated.
