=== External Media ===

External media (USB drives, SD cards) are auto-mounted by the Journal. No access restrictions are applied currently. If activities use these external ~~media~~ directly, they need to take care of ensuring data integrity since the user may (and will) remove the medium at any time.

External media (USB drives, SD cards) are auto-mounted by the Journal. No access restrictions are applied currently. If activities use these external volumes directly, they need to take care of ensuring data integrity since the user may (and will) remove the medium at any time.

Depending on the Linux distro version, the volumes appear as /mnt/*, /media/*, /run/media/$USER/*, or in other places. Sugar up to version 0.82 provided an API to access their [[#Mount Points|mount points]]. Nowadays you should use general Linux API to find the volumes. The recommended way is using the [http://developer.gnome.org/gio/stable/GVolumeMonitor.html GNOME Volume Monitor] with a fallback to [http://www.freedesktop.org/wiki/Software/hal HAL] (there is an example in the [http://git.sugarlabs.org/backup/mainline/blobs/master/backup.py#line671 Backup activity]).
