The reason I ask is because I am on my second 500gb Seagate in just over a year. Both developed the same problem which is the USB connection seems to work it's way lose from its internal connections, despite being gentle with it.
All I use it for it storing TV programs and movies and the odd file or two.
I saw a buffalo but my wife seems to think they are shit. She knows more than me about computers which is why I bought the Seagate in the first place!
Thanks
