I'm at home, have been since yesterday. Eating lots of solid foods because I'm getting all of my wisdom teeth removed on Wednesday.
Seagate responded to my email, reassuring me that the disk does not "click" as part of its normal operation. So, I think I'm going to send it back to *them* rather than newegg this time. Meanwhile, what's left of my old movies disk is filling up quickly. An average of three low-def shows per weekday means nearly 1G/day. And 30 minutes of high-def is 2G/show!
But at least I can transport the low-def shows in realtime over the internet and watch them here :)
