I purchase this Toshiba canvio 710 1TB hard disk from online. The hard disc has good design attractive colour and very very good build quality, but when I attach this to my laptop it tooks time to detect. I also tried this too many the other laptops but still face same thing. Data transformation rate is also very slow and the worst part is produce humming sound which is very irritating. I contact to the service centreI and they response me that it is not an issue it works fine either they are correct but still this things irritates a lot. I am using this from last eight month apart from the above mentioned problems it works fine
