I used seagate harddisk since 5 years and I does not faced any problem. Its a very portable slim harddisk with great sleek and slim look with very high speed of data processing. The harddisk is very powerful.
I have 500GB harddisk and the copy of data speed is upto 95mbps . I should be installed software directly to the harddisk and the speed is very gud.
And after using this I purchased 2TB seagate internal harddisk for our compter desktop and its work very easy.
Its easy to use and come with backup plus sofware.
