I purchased this device a few months ago and it is still functioning. Plug it into a Windows XP machine and it just works. I tried firewire, USB 1.0 and USB 2.0. Plug it into Linux (I've tried Knoppix and Fedora Core 3) and it will just work.
My only compliant is that it isn't a quiet drive. But if you can deal with a little bit of churning for the formated 186 GB of storage, it is a good deal.
Please note that I am unable to recommend the included software, as I have no need to install it.
