In this how-to, I will explain how I set up Ubuntu to quickly mount and unmount disk, USB devices, etc.
For UBS devices and drives, I used Disk Mounter, which is built into the panel.
The panel widgets will show
Click the Add button
Disk Mounter will appear in your panel as a box of mountable drives on your system, including USB drives, CD/DVD drives, and other mountable devices (iPod, audio devices, etc.).
To disconnect the device, I just have to click on its icon and select Unmount or Eject.
Disk Mounter allows me to quickly mount and unmount disk and devices even when I can’t see their icons on the desktop.
