Help swapping "dead" drive? [Case #15693780]

Some more ideas:

Was looking through the log from startup a few minutes ago to look for possible issues unrelated to the drive and found this:

Is that referring to the system RAM? I did upgrade the RAM to a 1GB chip, but wouldn't I have other issues if that was bad? Hmm that's the first thing I saw. Then this:

Not sure what the "RAID superblock" is, but that probably shouldn't be invalid. That sounds important. And lastly:

Someone must have an idea what this indicates, right? How can the drive be "Dead" or "Not present" if it tests fine in the vendor tool. Windows was excited for me to format it when I popped it in to run the tool. :)
