iPod displays wrong available spaces
I have added some songs into my iPod 4th generation, the iTunes shows that the remaining space is 9.71GB. However, when I open the "about" in my iPod, it shows that the remaining space is 18.4GB, which is weird.
Note: I have already erased the iPod and added the songs again, but it still shows the wrong information.
The S.M.A.R.T information is:
Retractor: 20
Reallocs: 0
Pending: 0
