I bought the 5 TB, I'm a little disappointed because I find it a bit noisy and it scares me because I nearly 4TB data above. On the main pc win8, I am of whim, suddenly I see you, suddenly I do not see you and it's painful because it is not permanently connected to the main PC for my home network is not performing. If I plug it into the PC's top Win7, it recognizes the first time. I have not tried yet on the laptop that is on win8. Its primary function is to be plugged into the USB WD multimedia and it is similar, it is capricious to connect .... I do not know if I should send it ... but I want to lose my data ... Okay, so, I do not know if I should recommend it. As against the WD external HDD no PB, I have 3 for quite some time and nothing to say, but alas, they do not go above 3 TB and are USB2. I had to return a previously 4TB of Samsung and I finally learned amazon that was equipped with a Seagate and this is home I've returned to Holland ... yet new .... I can tell you about their after sales service soon ...
