6748 with FATFS

Hi,

  I am using the 6748 LCDK with an SDHC card.  I have been able to create folders and a file within the folder.  When I try to open the file in pspad editor, I receive a message "cannot open file with the file path and name"  The data is a bitstream 128 bytes in length.  When I open it in wordpad, I can see the ascii equivalent text.  I am performing a f_open, f_write followed by an f_sync, then an f_close.  Am I forgetting anything else?  Could this be a pspad issue?  I have never had an issue with any other byte data files till now.

Thanks,

Will
