Summary: I bought the 1TB version over 3 years ago and it still works. I had Windows XP at the time and now I use it with Windows 7 64-bit. So I'm not sure why the other reviewer had a problem, maybe it's because they were updating their OS while mine is pre-installed?
Summary: OK, it's big and it's fast and I haven't filled it up yet. However. I don't like that it has no actual on/off switch. This has been an issue, and I don't know if it's the drive or the computer, but every once in a while I get a glitch and it disappears from the system.
Summary: Great external hard drive. Plenty of space for what I need. AC power is a pain but I knew this going into it. I rated 4 stars because I wish it were a bit smaller and had a firewire connection to speed up transfers.
Summary: Good price, very simple. Just plugs right in with a USB cord and then you have to follow on screen instructions to partition it. If you never heard of that it is very simple and you can just follow the on-screen instructions. Great product.
Summary: This is the only brand of external hard drive that has not caused me trouble when using it with my Mac. This is the second unit I've purchased for school to store video files. It's perfect to use with iMovie.
Summary: I bought this to use as an external edit device to hold video footage and photos. I was absolutely stunned that the drive did not come with a firewire port; this mini usb is slower than molasses in January! A simple save, which should take all of a minute, turns into a 5 minute process every time.
