Changes in physical drives are stored in the tblFloppyHist database table. You can open the Changes By Type page in the Reports tab and select the Floppy item on the left.
Keep in mind that, to save database space, history tracking is disabled for most scan items by default. You need to ensure that the History checkbox for the FLOPPY item is ticked under Configuration\Item Wait Time (Lansweeper 5.3) or Scanning\Scanned Item Interval (Lansweeper 6.0). If you tick this box now, only
future changes will be detected. It is not possible to report on changes that occurred prior to enabling history tracking.
