Hi there, I just purchased a 1TB Samsung Story Station. I am backing up some files from my PC and get an error message before it even reaches 30gb saying that the hard drive is full? When I first got the drive I connected it to my PC and put some files on it. Since then I have also connected it to my Mac and and takes some files from my PC and transferred them to the Mac using the Story Station. Can anyone tell me why I am getting the error message saying it is full when there is only around 30gb being taken up? Thanks.
