I bought one of these a month or so ago, to pair up with my macbook, just for general storage use. I haven't been using it much, but it seems to be having a few problems when i do.
While I am using it, it seems to randomly unmount itself and i get the unsafe removal message. no warning or indication why it might be doing this, does this sound like any known issue?
I spent about 3hrs using mine yesterday. I did one copy that lasted an hour and a half... No problems...
Can you try it in another machine?
