I have tried mp3 files and a flac file, i checked the tags on the file, they were both already tagged, one from the band i bought the flac from the other from the mp3 that the band provided. I have used files from both of the sources and they are currently on my Fuse. It is not only the tags though, it is the new music that i have loaded, after unpluging all that remains is the name of the song basically, and even when plugged back in the computer that is what is left.
I did have a hard drive faliure and tried to copy the files on the fuse back to my new hard drive but when i tried to play them they came up that they wouldn’t play on my computer but they still are still on the fuse and play. This is probably unrelated to the current problem but i thought i should mention it.
