- Mount the Windows drive.
- Open the Terminal application and type:
% cd /Volumes/Windows_Drive_Name
This will find all ._* files, delete them, and print to screen a list of all files deleted.
% find . -name "._*" -exec rm '{}' \; -print
[Editor's note: I haven't tested this one myself, but you might want to put a "-i" after the "rm", which will force you to say "yes" to each file that is about to be deleted ... at least until you're certain the command is doing exactly what you want it to do.]
