The Mount Tray application is used to facilitate the mounting and unmounting of filesystems on internal disks and USB storage devices. It is included in the system tray, meaning that in can be used within any window manager that provides a system tray. If you remove the icon from the system tray, you can re-add it using Control Panel/10.1 → Mount Tray/10.1 or by opening an xterm and then typing pc-mounttray &.
When you insert a USB drive, a "New Device" message should appear in the system tray, followed by a message indicating that the device has mounted. The contents of the device should then be displayed in the default file manager for the desktop. A list of available file managers can be found on the Files and File Sharing page.
In the example shown in Figure 8.13a, a USB device was automatically mounted as it was inserted. The user then clicked the Mount Tray icon and its "More Options" menu.
The following options are available:
- Open Media Directory: click this if the default file manager does not automatically open. If the desktop does not provide a default file manager, Mount Tray will provide an "open with" dialogue so that you can select the utility to use to browse the contents of the USB device.
- View Disk Usage: in the example shown in Figure 8.13b, a UFS formatted USB device is mounted at /media/USB-Device. The amount of disk space used by the system hard drive and the USB drive is shown in both GB and as a percentage of available disk space. The mount tray will turn yellow if disk space is over 70% and red if disk space is over 90%. If the internal disk drives are partitioned with any other filesystems, these will also appear in Mount Tray. Table 1.3a lists which filesystems are supported by Mount Tray.
- Rescan Devices: click this option if an entry for the USB device does not automatically appear.
- Load ISO File: used to mount an ISO to a memory disk. When the ISO is unmounted, the memory disk is also detached from the system.
- Change Settings: as seen in Figure 8.13c, this screen allows you to configure how often Mount Tray checks the disk space used by mounted devices. Leave the checkbox checked if you would like it to automatically check disk space when a disk is mounted.
- Close Tray: click this option to remove Mount Tray from the system tray.
When you are finished using the device or filesystem, click that entry's "Eject" button. A pop-up message will indicate that the device has been unmounted and that it is now safe to remove the device.
