Marvin: In addition to the suggestion for keeping your batteries at a higher rate, you might also want to change the Default Folder in Book Port Transfer. Doing this, will allow everything you send go into a different folder, other than the root directory of the card, which will cut down on the need to have to reformat the card or run check disk so much. If you do this, any folders you create in Book Port Transfer will be under the new Default folder. You can change this by going into BP Transfer, Options, Advanced, and tab down to Default Book Port Folder.

First I have a book port that is approximately four months old. I am using a 1 gb flash card and my operating system is windows me. After I send a few files to the unit or record a memo, I am taken back to the beginning of the present file that I am reading. All my bookmarks also are cleared. Then I have to run scan disk and the book port works fine. The thing is this happens quite often and as a consequence, I have to run scan disk frequently. I was wondering if anyone out there had any advice on how I night cut down on the amount of errors that come up. Any advice would be appreciated. Marvin Kotler
