Like my other USB flash drives (all of the other party, between 8-32GB so far), I also have this quite often had to use and especially film and television recordings stored there and played on the PC. Actually everything went fine ... until then no longer ran for almost 3 months. The drive must be formatted. Despite all attempts to save all the data are (now well 40GB) lost. - The girlfriend was exactly the same, just 2 months.
That's been happening to me with anyone yet stick, although they were also often used - and sometimes for years. Can So unfortunately only advise against the purchase (or much more warning!).
