Author  Topic  frant Starting Member 2 Posts Posted - 2012-02-27 : 07:48:54 Has anybody else noticed that the Data Collection Report for Disk Usage seems to show the wrong results. Selecting a database from the original disk usage report show a graph of usage over a period of time. I cant make head nor tail of the Unused Size column and display on graph this bears no resemblance to the actual size of the database files etc. For example. Database File size 18GB Used Space 15GB Unused Space is showing as about 20GB Has anybody else noticed this , or if you you understand what this data is showing me please let me know. Thanks Francis
