I have a Creative Zen and I recently had to reformat the removable disc for it. When I redid the disc in Mac OS Extended, the player said it didn't recognize the file system, so I tried MS-DOS format... Still no go. Lastly, I tried UNIX, and it recognizes it on my Creative Zen, but now, when I go into removable disc mode, the computer doesn't recognize it anywhere. I even tried booting up in Linux, and it won't show up. Is there any way at all that I can retrieve the data? Should I try using a Windows computer instead?
