I bought this external HDD for office work. But this HDD is not working properly. Data copying speed is very slow. And some time, while copying the data file is a process that the HDD is warming up to at the time. The price of this HDD is not cheap, compared to the quality of the HDD. I have many time raised HDD heating issue with the lenovo costomer service. But they are not supporting my issue. I am very disspointed with Lenovo serive. This HDD not userfriendly to use. It has no value for money.
