-Mode 1 is fully handled (`Mode1Cooked` for the ready-to-mount user data, `Mode1Raw` for the complete 2352-byte sector). Mode 2 is *detected* (`Mode2Raw`) but its per-sector XA payload extraction is left to the consumer. The full workflow — detect, save, and platform-specific mount commands — is in `examples/save_data_track.rs`.
+While audio data is PCM, with non-audio data it is up to you to detect and parse it. It can be a mountable image or it can be something else. Mode 1 is fully handled (`Mode1Cooked` for the ready-to-mount user data, `Mode1Raw` for the complete 2352-byte sector). Mode 2 is *detected* (`Mode2Raw`), but you need to interpet the data by yourself. You can see a full workflow — detect, save, and platform-specific mount commands — in `examples/save_data_track.rs`.
