Now my problem has been solved with the help of linux.
I got a hint from this blog:

My case is very similar to this one. I have Ubuntu 8.04 installed on my laptop, and the problem was solved in this way:
1) sudo fdisk -l
Result: Cybook was found as sdb device.
2)sudo fsck.vfat /dev/sdb -artvVw
The process took about 6 minutes for me. Some bad clusters were found and repaired, which correspond exactly to the file unsuccessfully copied.
Hope this can help others who have similar problems, and flowers to those enthusiastic to help.
