You can disable the internal caching layer by checking the check box Enable file system caching in the preference pane This will reduce performance drastically and is not recommended The reason that you may want to do this could be that you are worried about data consistency in the event of a system crash For instance if you re running a database from the NTFS volume you d normally want as few layers of caching as possible to guarantee the correctness of the data This option is offby default 4 2 2 For a volume To disable the caching layer for one specific volume select the volume in the Vo umes section of the preference pane and check the box Disable file system caching This setting is governed by the control file Tuxera NTFS disable caching When this file is present in the root of a volume when mounting caching is not activated when the volume is mounted To manually revert this option you can delete the control file Inc It lahdenkatu 23 A 5th floor 00210 Helsinki Finland http www tuxera com TUXERA NTFS for Mac USER GUIDE TUXERA 10 13 4 3 Enable debug logging Ifsomething doesn t seem to work properly in Tuxera NTFS for Mac or you want to find out what happens when you attach an Tuxera NTFS for Mac volume for troubleshooting purposes you can enable debug logging to get more information on what happens during the mount process Tick the checkbox called Enable debug logging to enable this exten
