So what is going on? To clarify: /mnt/win is busy means that there is some program running that is "using" something on /mnt/win, either as a current directory, or it has a file open.[1] You can use the /sbin/fuser command to see which programs are using /mnt/win. It returns the "process ID" of each program, and a character representing how the filesystem is being used. You may need to be root to see all the programs. For example, $ /sbin/fuser /mnt/win /mnt/win: 3425c $ ps 3425 PID TTY STAT TIME COMMAND 3425 pts/2 Ss 0:00 -bash So a bash command is using /mnt/win as a current directory, and it's on terminal pts/2 (probably your second terminal window). See man fuser for more details. fuser is part of the psmisc RPM. Hope this helps, James. [1] There are a few other possibilities: see man fuser for details. -- E-mail address: james | "This was, apparently, beyond her ken.
