I have a 2nd generation iPod Shuffle. The first two times I loaded it up almost all the disc space was used. I had reserved 0% for data. Starting with the third load, roughly 1/9 of the total space was unused, thereby storing about 3 CDs’ less worth of music. I checked the amount reserved for data, still 0%. I auto-filled everything again from my chosen directory, still the same problem. I also then restored to the factory settings hoping that starting from scratch would eliminate the problem but no luck with that either. Other than this issue, the Shuffle works perfectly in every way. Has anybody had a problem like this?
