Because, with "shortname=lower", copying one FAT filesystem tree to another FAT filesystem tree using Liux results in semantically different filesystems. (E.g.: Filenames which were once "all uppercase" are now "all lowercase"). And from recently email http://bugs.debian.org/476903 http://bugs.debian.org/497121 http://bugzilla.gnome.org/554031 https://bugs.launchpad.net/ubuntu/+bug/290362 My usual answer for it is, personally I agree that "winnt" or "mixed" is proper. However, it is long-standing default behavior. Um... But, now, situation would not be same with long past (didn't have shortname= option). Well, so, what do you think about changing the default of vfat from "shortname=lower" to "shortname=mixed"? If default was changed, the shortname (8.3) will not changed to lower case to show. And if possible, it will try to preserve created shortname. Thanks. -- OGAWA Hirofumi This causes Linux and Windows to display filenames the same.
