As is the description it is my first hd but sadly it needs power to run. Hd is very good in terms of read and write ratio. Out of 1tb only 989gb is available. Formating of the hd is also v easy.
It can be connected to any pc or laptop and also to tvs for entertainment purpose. If its not detected format it ntfs file system to be tuned to Windows 8 or 7.
For apple macintosh also it detects and works like a charm.
Finally a very good buy if you want to dwnld and save files and pics for future. Uts a must need
