    I have bought WD drives, no problems. I bought this Seagete 1TB drive for my iMac using "TimeMachine" backup an had nothing but problems. 1. Couldn't shutdown my computer with out pulling the plug. 2. I couldn't invert the colors on my screen when I had it connected. 3. I couldn't reformat drive because it say's that I haven't any permissions. I click on "get info" on Seagate and it was set to read only. I changed it to read and wright, still can't format the drive. So I just wasted money on a fancy paper weight.

    Got this as a gift for someone, great for adding to your x box one and loading ALL your games and still having room. Makes your x box faster without everything loaded on it. Also can be formatted for photos and music and so much room!
