I bought this sony hard disk about a year ago but I am totally dissatisfied withBje working of it.i had to visit it’s care for approx 3 time till now.once for the purpose that it got corrupted secondly for the usb and thirdly that after 40 gb of data it shows no space .so I m fed of this product .this review is just an experience of mine that can differ from others too .and one more point I want to mention is that it’s customer service in patna is also not too good , they takes a long time to repair.it also has a good thing that it’s transfer speed is little high from others, but overall thumbs down to this product , I will not recommend it to anybody.
