Many NSA features require a valid internal volume.

Features like the print server, download service, broadcatching, FTP and Windows/CIFS 
access will not work without a valid internal volume. Make sure you have a volume on an 
internal disk and that the volume is in the healthy state.

• Install an internal disk if one is not installed yet or has failed. See the Quick Start Guide 

for how to install an internal disk.

• Create a new volume if you do not have one on the internal disk yet.

• Make sure the volume on the installed internal disk is in the healthy state.

I set the media server function to publish a folder, but some of the files in the 
folder do not display in the list on the media client.

Files with formats that are not supported on the media server may not display in the list. See 

 for the file formats that the media server supports.

I published a folder with the media server function, but the media client does 
not play some of the files (or does not play them properly).

1 Files with formats that are not supported on the media server may not display in the list. 

See 

 for the file formats that the media server supports.

2 If you are using media client software, you may need to install codecs on your computer. 

Since the media client software uses your computer’s installed codecs, files do not play 
if the required codec is not installed on your computer. 

3 The media client may not support the file’s format.

iTunes does not display the names of all the music or video files I just put on 
the NSA.

1 Make sure the files are a format supported by iTunes. See
