Fragmentation
If pictures cannot be recorded/reproduced
properly, try formatting the recording medium.
While repeating picture recording/playback with
a certain recording medium for an extended
period, files in the medium may be fragmented,
disabling proper recording/storage. In such a
case, make a backup of clips in the medium then
perform formatting of the medium using
"OPERATION" > "Format Media" (see
page 108) in the setup menu.
