Defect. Not the brand I recommend. Many of their products require full testing upon receipt. (Max upload large files or duplicate a large file) I bought this last June but only now almost a year later when I started filling it I see there is a problem. Once you store more than a few gigabytes, it just shuts down when copying files. Reformatting doesn't help either. So now I've paid a lot of money plus shipping from the US for a useless piece of crap. Which will not store more than a fraction of its capacity.
