I have an external HD that is Mac only, and I have been using it for months now and everything has been fine. I have not done anything differently, haven't tried hooking it up to a windows machine or dropped it, nothing like that. But all of a sudden two days ago I can no longer write to the drive. I can read from it, but when I try to write to it the file stops after only maybe 1/10 of the file has been written and then it says that the drive has been ejected. If I do not try to write to the drive then it stays connected just fine. Anyone have any ideas? I've tried searching around for solutions, but I am having a hard time finding my problem. Thanks for the help.
