Nikon DS-L4 Instructions Manual page 28

Initializing recording media
Before you can use a microSD card, USB memory drive, or other recording media with the DS-L4, you must initialize
(format) the media by using a PC.
When initializing recording media, you can specify a volume label, which is displayed in the screen for setting image save
destinations, and can be used to identify the media. We recommend that you specify a volume label when initializing
recording media. For recording media devices for which no volume labels are set, strings EXT1, EXT2, EXT3, ... are
displayed.
Backing up data
Note that, initializing storage media renders any data saved on the media unusable. Back up any important data (to a
PC, etc.) stored on the media before initializing it.
Setting the image storage and playback folders
The DS-L4 allows you to connect multiple recording media devices, and to switch the storage folder and playback folder.
Before you start capturing images, you must specify the recording media and folder as the storage location for the
captured images.
For details about setting the image storage location, refer to "8.2.3 (7) Specifying the destination media and save folder".
Errors with media
Make sure that recording media is inserted to the DS-L4 before saving or
playback data.
If an image is not saved or replayed correctly for any reason, a warning
message is displayed.
If you see such a message, remove the media once, and then re-insert it. If the
message persists, that recording media may be no longer usable. In such a
case, use other recording media or initialize the failed media by using a PC.
An error may be displayed when the amount of free space on the recording
media is low. Check the number of images that can be captured in [STILL
IMAGE SETTING] of [CAMERA MENU: SHOT/REC]. For the remaining
recording time, see [MOTION IMAGE SETTING] in [CAMERA MENU:
SHOT/REC].
