Does anyone knows how to unmount a drive in java in OSx
I am trying to unmount a sdcard from java. I am using java Swing class and the drive gets mounted automatically, but how do I unmount it.

"I am using java Swing class and the drive gets mounted automatically" <-- I very much doubt Swing is responsible for this at all – fge Jan 03 '12 at 20:50

++ to Michael Dautermann. That is the solution you should follow. – Chris Aldrich Jan 03 '12 at 20:56

In Java 7 `FileSystem.close()` might imply an unmount. But it is neither mentioned, and neither do I know the availability of Java 7 on OSx. – Joop Eggen Jan 03 '12 at 21:05

The concept of mounting/unmounting is not platform agnostic, so it doesn't exist directly within the Java APIs. You will most probably have to issue a command line call to unmount by using Runtime.exec()
There might be open source libraries available that wrap this exec call for you, but I'm not positive.

I have a error in Java Swing class while unmounting an SD card. The following works fine with command prompt "umount -f /Volume/ NO \NAME/". Now if I have to write the runtime.exec() by passing the directory path from swing class I can generate the following command, "umount -f /Volume/ NO NAME/". How to work around the problem of space in java – Arindam Bhattacharjee Jan 03 '12 at 22:31

You could call umount using Runtime.exec. Of course, this solution is not portable.
