Recording processing does not end normally if, for example, the POWER switch on the rear panel is turned off during recording, or if the power cord is disconnected during recording. Because the file system is not updated, video and audio data recorded in real time is not recognized as files and clip contents recorded up to that point are lost.
However, this unit has salvage functions which can hold losses to the minimum by reconstructing clips on such discs.
There is a quick salvage function which executes automatically and a full salvage function which you can execute as required.
Quick salvage: Clips are reconstructed on the basis of backup data stored in nonvolatile memory and markers recorded on the disc. Processing time is about 5 seconds.
Quick salvage executes automatically if the unit is powered on with a disc still loaded after recording was interrupted by power off.
Full salvage: Clips are reconstructed on the basis of markers recorded on the disc. Nonvolatile memory cannot be used, so processing takes longer than for a quick salvage (about 30 seconds, although it depends on the state of the disc).
You are prompted to execute a full salvage whenever you insert a disc that was removed manually from a powered off device after interruption of recording by power off.
Note that no recorded clip contents are lost when the on/ standby switch on the front panel is set to standby during recording, because the unit does not enter standby mode until after the end of recording processing.
Notes
•Even after recording finishes, do not set the POWER switch on the rear panel to off until the ACCESS indicator has gone out.
•These functions salvage as much recorded material as possible after an unforeseen accident, but 100% restoration cannot be guaranteed.
•Even when these functions are used, it is not possible to recover data from immediately before the interruption of recording. The amount of data lost is as follows.
Quick salvage: From 2 to 4 seconds of data before the interruption of recording.
Full salvage: From 4 to 6 seconds of data before the interruption of recording.
(More data may be lost when the unit is subject to vibrations, and when you switch frequently between recording and paused.)
•You are prompted to execute a full salvage every time you insert a disc that has not been salvaged, or power the unit on with such as disc loaded.
•No recording is possible on discs containing clips that have not been salvaged, although it is possible to play back the normally recorded sections. Recording becomes possible if you perform a quick format, but this erases all of the original recorded content.
To restore clips with a full salvage1 Insert the disc on which recording did not end normally.
The message “Salvage ?” appears on the display.
To cancel the clip salvage
Press the RESET button.
Notes
•The message “EJECT?” appears when “REC INH” is displayed in the operation modes section of the display. If the disc is write protected, eject the disc, set the Write Inhibit tab to enable recording, and then insert the disc again. If REC INH on page P1 of the function menu is set to “ON”, set it to “OFF” (see page 89).
•This operation cannot be cancelled once it begins.
•Before using another XDCAM device 1) to perform a full salvage of a disc that was recorded successfully on the

2 Press the SET button.
Processing begins and the message “Executing.” appears.
When processing finishes, a message appears to display the results.
If the message reads “Incomplete!”, the clips that failed were lost.
