Thanks for this. I googled the phone number and found the email address for the company that handles Samsung's outsourced tech support. I emailed them about needing a new power adapter for my SE-S204S, and they emailed me right back, asking for my drive's serial number and my mailing address.
Looks like I'm getting a new power adapter for free. Thanks Samsung!
