My operating system is Windows 7.
Automatic start, SD, after connecting to a USB socket and the stop button open. Driver installation is fast and the HDD is immediately operational. On sufficient weight to stand properly seated on the carrier. Matt black color, a nice effect, its size is minimal and it is not noisy in operation.
No special knowledge is required for using this external HDD.
I do not use automatic backup program so I can not confirm the problems mentioned by at least one commentator. I prefer to save myself, from Windows backup by selecting the files to be saved on the HDD.
Conclusion: Given a delivery on schedule and satisfaction I draw from this material I can only recommend.
