I used this harddrive for approx around a year. As it is a 1.5 tb hard drive I had stored around 500 GB of data in my extetnal harddrive. But I dont know I my harddrive got crashed and I lost all of my important data. As the data was so important for me I had suffer from lot of problems. They gave me a warranty but they denied to restore the data at that time. I was shocked to pay such a huge amount of money for a useless thing. I request you all to not buy this harddisk as I have seen the quality of it.
