Dan I have this issue as well. My drive has 700GB free, but even after copying a few small files I get this message before every one. Would it be possible to add an option to "disable" the space check all together? Thank you for your continued work on this. I'm fortunate to live in an area where our Cable Company hasn't gone overboard on copy protection. Only the major "Premium" channels are copy protected, so I record & transfer extensively from my TiVo. I'm sitting on two Roamios with the old interface just to ensure I don't lose this capability. EDIT: To answer your questions about the space issue.. the file sizes for the files being transferred does show correctly, as does the "Free Space" on the settings screen.
