Using an SD Card
Checking the Remaining Recording Time on the SD Card
When the camcorder is in 
mode, the display on the upper left of the screen indicates which SD card slot is in use and the available recording time (in minutes*) that remains on each SD card.
42On the [Media] status screen (A143), you can check the total space, SD speed class, used space, available recording time and available number of photos on each of the SD cards.
* The approximate available recording time is based on the current bit rate (A51).
Recovering Data on an SD Card
Some actions, such as suddenly turning off the camcorder or removing the SD card while data is being recorded, can cause data errors on the SD card. In such case, you may be able to recover the data on the SD card.
Operating modes: 
1 Insert the SD card with the data to be recovered into the camcorder.
2 When the screen prompts you to recover the data, select [OK] and then press the joystick. 3 When the confirmation message appears, press the joystick.
NOTES
•In some cases, data may not be recovered, such as when the file system is corrupted or the SD card is physically damaged.
