Kathy: I wouldn't worry too much about Book Port's opinion of the free space; there is a free space bug where 4GB cards are concerned. As for the other problem, you might try reformatting. >>> kblackbn@xxxxxxxxxxxxx 07/03/06 06:16AM >>> When using a 4 GB compact flash card, I sometimes get an odd error message that sounds like "Buffer overflow; moving on." The BookPort speaks this repeatedly until I do a reset. Also, no matter how many files are on this card, BookPort reports there are only "1 kilobytes" free. Should I reformat the card?
