Moving back to the main menu, I next wanted to explore the USB capabilities of the box. Using the front USB 2.0 port, I plugged in and used both a FAT32-formatted USB memory stick and an external-USB hard drive. Both worked fine, except my USB drive was partitioned into four parts, and the DSM-520 only saw and mounted the first partition. The DSM-520 allowed me to browse through the file system choosing pictures, music or movies.
The only odd behavior occurred during the time I was browsing a directory with photos. When using the server, I saw little thumbnail images, but in USB mode, the area where the thumbnail should have been was black (Figure 10).

The other area available from the main menu was the Online Zone. This feature, shown in Figure 11, allows you to use premium, i.e. paid content, from several providers. Using these options for the most part required going to the appropriate Website and signing up for service.
