Mac owners have a habit of cluttering up disks that will be used on other
systems with files like .DS_Store ._.DS_Store and ._SOmeName.

Every time a folder is opened on a mac, at a minimum, a .DS_Store file
will be created.

The following commands are useful :

    # cd to where ever your CF card is mounted on your mac 
    cd /Volumes/CFILIAD

    # find all files with name .DS_Store and delete the rascals
    # from the volume
    find . -name \.DS_Store | xargs rm  
 
    # find all files in directorys in and below the current 
    # and remove all files that start with a ._
    find . -name \._\*  | xargs rm

    # Remove all files and directories in directories in and below the current
    # that look like .Trashes
    find . -name \.Trashes | xargs rm -rf

Its is a good idea to drop off the xargs stuff first to see exactly
which files will be feed to xargs an then to the rm or rm -rf command.

Note the .Trashes files are directories and so one needs to add the -rf
to the rm command.

After you have cleaned up the card you can back it up to a folder
on your Mac by using a simple rsync command.

#!/bin/sh
# Note this does not delete files from the target
#  Add --delete to delete files on the target that are not on the source
rsync -av --delete /Volumes/CFILIAD/ /Users/jerry/CardBackup

Please read the man pages before trying these commands...
