I recently purchased a WD 1TB Element External HDD through Times Shopping for Rs.3,600. I want to know whether it needs any power supply for working or else it can be directly connected through USB for both power and data transmission.In the advertisement they have indicated that it comes with an AC adaptor wheras when i searched for the same product in their website it says no need of ac adaptor.I am totally confuse and want to know how it works????
Yes, it comes with an AC adapter and it is required. you can see it in the last photo and it's listed in the specs/details.
Thanks a lot. So, you mean to say that without the Ac adaptor we can't use the device for tranfering data from the laptop.and also, i want to know the diff between the one with tha ac adaptor and the one without the adaptor. Is th price what i paid was the right one....
Like I said, that particular model requires the adpater to use at all times regardless of which computer you use it on.
You didn't list the model without an adapter, but my guess is it's a 2.5" drive instead of a 3.5" drive. 2.5" drives require less power so some can be powered via USB. 3.5" drives usually require more power than a USB port can provide, thus it needs an adapter.
