Peter, you may want to do a chkdsk on that drive to make sure all is in = order. >>> peter.rand@xxxxxxxxxxxx Saturday, October 09, 2004 3:07:12 PM >>> Larry/Rob, While using the Book Port today with a 1GB Kingston CF card, I got the =3D following error messages: When I pressed the "2" button while listening to a book to pause =3D text-to-speech, I heard: 'Application file write error' While browsing some MP3's in a sub-directory, I heard: 'FS Memory. Out of DROBJ structures. Error accessing index file. There are = =3D no files.' This error locked up the Book Port, and I had to remove the =3D batteries to reset the unit. The reset corrected the first error above, = but =3D when I browse the affected MP3 sub-directory, I repeatedly get the same = =3D error message. FWIW, the sub-directory contains 38 MP3s.
