The windows drives are mounted at boot-time using pysdm. The setting were
nls=iso8859-1,users,umask=002,sync,user,dirsync,uid=mtk
When I try to change the permission of files using chmod, I don't see any update in the permissions. Chmod quietly returns the prompt. Also the permission of created files must have been 755 instead of 775. Here is the output of terminal.
mtk@mtk-laptop$ umask
0022
mtk@mtk-laptop$ touch abc.txt
mtk@mtk-laptop$ ls -l abc.txt
-rwxrwxr-x 1 mtk root 0 May 14 00:00 abc.txt*
mtk@mtk-laptop$ chmod ugo-x abc.txt
mtk@mtk-laptop$ ls -l abc.txt
-rwxrwxr-x 1 mtk root 0 May 14 00:00 abc.txt*
mtk@mtk-laptop$
Does anyone know what is the issue behind this?
I am using ubuntu 12.04.
