Query: Unreliable

Worked well right out of the box. I connected it to my home network, and within a few minutes was able to connect from XP, Vista and Mac PCs. In the evening it was gone from the network. Re-powering and resetting did not help, and it doesn't even look like it goes through the normal boot up process. The drive is spinning, I can hear it, but it no longer connects to the network. It is being returned. For a device that was to house backups of all of my data, images, etc, it is too unreliable.
