       This manual page documents briefly the rio command.  This manual page was
       written for the Debian GNU/Linux distribution because the original
       program does not have a manual page.

       rio is a CLI controller for a Diamond Rio MP3 file player.

       The default ioport is 0x378.  If this is not the ioport for your printer
       port, you will have to use the -p option.

       Initialization should only be performed on new or corrupt cards.  You can
       initialize with bad block checking enabled (-iy) which will test all
       blocks on the internal or external flash ram (which ever is selected) and
       note all bad blocks. This process will take some time (upto 20 minutes on
       slow machines).  You can also initialize with bad block checking disabled
       (-in) which is much quicker but all blocks (even bad blocks) will be

       If you want to delete all files on the device, the (-za) option should be
       used instead of using the initialization options mentioned above.
