Xbox Power-cord Replacement Program for No-charge [rev1]

A problem has been found with Xbox power cords that can cause burns or damage to the console when submitted to sustain over voltage or mechanical malfunction.  The power cords affected were manufactured in the United States before October 23, 2003 or Europe before January 13, 2004.  Record the serial number and manufacturer date found on the bottom of the Xbox and then go to <http://replacements.webprogram.com/en-us/index.asp> to receive your no charge replacement.

Microsoft recalls Xbox power cords - <http://news.com.com/2100-1043_3-5580586.html>

When checking multiple consoles on the web site, make sure to clear your cache and I would even go so far to try it multiple times.  I was able to register one Xbox for the replacement and then another came up fine, when I went to register the third it said it didn't need the replacement at first, but after trying again I was able to order a replacement.

Now my question is I have multiple Xboxes in the house and power cords have been shuffled around in the past.  How do I identify which power cords are faulty?  Additionally, one Xbox was manufactured on September 9, 2003, which is before October 23, 2003, yet the web site and automated phone system [number in FAQ] says it's fine, how can that be?  I called and then pressed 0 twice to speak to someone, but was disconnected after a few minutes.  Microsoft needs to promptly address these concerns with the contractor.

Update:  I finally talked to someone at the Xbox Power-cord Replacement call center and he basically told me “I have no idea.”  Luckily he ordered another cord so I could replace all of them.  However, he didn't know how I could tell which power cords would be effected, other than to look at the new ones and compare/contrast.  Also, he didn't know why the system would deny an Xbox that was manufactured before October 23, 2003 based upon the serial number.  I was thinking about it some more and Xbox Support had refurbished my old unit with a brand new one since mine was damaged in transit upon requesting them to fix the damm DVD drive [this being the second time I needed it replaced!].  Maybe since it was refurbished and a new serial number, it wasn't in the system correctly.  It's incredibly unfortunate that the contractor isn't making a better effort to resolve problems customers are experiencing and as a result it reflects negatively upon Microsoft.  I'm going to try bringing up these issue with Xbox Forums and Major Nelson.
