some sectors of the card may become unreadable, or they cannot be written again, or they have other
problems.
Since software version 0.7.0 this type of sporadic failures do not cause a general malfunction of the
system, as the system is now to operate without flash memory, allows performing maintenance
operations on it (for example, a formatting), or even replace the SD card if necessary.
The
Vigilant
allows three possibilities for permanent data storage:
•
Use the internal micro-SD card for storage (default option).
•
Storage disabled, by selecting this option from the Storage menu. Timeline function will be
disabled in all the widgets, and the Trends widget will not work at all.
•
Use temporary data storage. The data will be written only in the RAM memory and thus it will
get lost as soon as the system is rebooted.
Temporary data storage option is activated automatically if any error is
detected on the SD card during the system start-up.
If the system detects any type of anomaly in the reading or writing on the card, this event will be
notified to the user by means of the Exception indicator in the navigation bar.
In the Storage menu, in System, it is possible to configure the equipment to work without storage, as
well as to format the SD card in case it is not being used.
Using the Rescue mode at the start-up of the system it is also possible to perform some operations
with the card, such as formatting it.
Otherwise, please contact
Vigilant
if you need to replace the SD card of your system or if you are not
sure about its integrity. In following chapters, it is explained how to perform a Micro-SD card
