When i put something large on my ipod in disc mode, such as a movie trailer or a large movie file and then remove it why does it still show up as having the same amount of space? why doesn't it revert back to the amount of space it had before? it happens with my compact flash memory card. The only way i could free up space was by reformatting? Is it somethign to do with the mac extended drive format? heres an example incase I'm not being clear. 20gb iPod - 11gb music. Transfer files over coming to a total of 4 gig So the iPod has 5gb free But when i delete it why do i still only have 5gb free? i should be back to 9gb free once i delete it? I'm not talking about the amount of space that you lose by default, ie 20gb iPod 19gb free etc. I'm talking about reclaiming the space once something has been deleted. Anyone know what I'm on about?
