Zune Giving Me Different Readings & Saying My Phone Is Filled

[deadwrong03]

anybody else having this issue? i synced it yesterday and had about 180 mb free, today i synced it and added only one song and now its saying i only have 77 mb free.

and i noticed last week i was adding songs and i had 2gbs free, but when i tried to add more it said it was filled to capacity so i removed alot of pictures and maybe 5 albums to free up space.

is the bar at the bottom of zune supposed to be completely black when its filled? anybody else having these kind of issues with zune?
