I mount the fat32 in /mnt/c, and run 'ls',it reports "Unicode name contains a character that cannot be converted to chosen character set.Remount with utf8 and this should work',what it means, the file name isnot Engilsh!

It means that the filename is not English, and the character set you are using (probably US English) does not contain non-English characters (accents, umlauts, etc), so the filename cannot be displayed properly.

The UTF-8 character set does contain non-English characters, but you are not using it to display the filenames when you mount the drive; this is what the error is instructing you to do.

If you are mounting the drive manually, use mount -t vfat -o utf8 /dev/hd* /mnt/c; if you are mounting it via /etc/fstab add utf8 to the options already in the line relating to this mount point.

If you are confused by how to edit /etc/fstab, please post the contents of /etc/fstab and we will help you further.

In the meantime, you could also read man mount (type this into a terminal window to see the manual for the mount command; page down to "Filesystem-Specific Mount Options" and read the options for the vfat (FAT32) filetype.

Hope this helps.

Thank you for you help,ereryting is OK now!
