http://www.linuxquestions.org – Hello I came to know about this bug or something in Ubuntu only in karmic version which slows down file transfer . I've used ubuntu from version 8.10 and having considerable speeds like 3-4Mbps sometimes 2.5 to 2. Even though very less its seems okay for me transfering a big 5G file or a movie to external Hdd without stucking and allowing me to do other work. (HowTos)
