operation according to the embedded REC or STOP 
command.

Exchanging discs
Even during recording, it is possible to eject discs by 
pressing the EJECT button on the front panel. After a disc 
is exchanged, the unit resumes operation according to the 
embedded REC or STOP command.

This unit begins recording operation about one second 
after the camcorder.

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 button 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.

• 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.

• When recording on the PDW-HD1500 does not end 

successfully, you can use another XDCAM system to 
perform a full salvage of the disc. As the other system, 
use the PDW-700.

• The following alarm message (see page 117) may 

appear when you insert a disc:
“DISC CANNOT BE RECORDED. FORMAT DISC 
OR CONTACT SERVICE TO RUN CLIP SALVAGE 
PROGRAM. (XXXX)” 
This message means that recording on that disc did not 
end normally. The “XXXX” in the message is a code for 
XDCAM devices that can salvage the disc. Refer to the 
following table and use one of the indicated devices to 
salvage the disc.

a) Does not appear on this unit.

• 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.

Insert the disc on which recording did not end 
normally.

The message “Salvage ?” appears on the display.
