Step 1: Install the Mac Air Superdrive on a Mac Air. Of course if they wanted to do a truly definitive test, they would need to take the next logical step as follows: I tend to believe them as well, but their methodology for determining this is flawed. Read the article and you will note they comment about the short cord limiting positioning of the connected drive. The drive showed up and you could click on it and view contents in Finder, the moment you tried to copy a file from it, it froze. It seems as there was enough insertion loss in the extension cable to cause the drive to stop responding when a file was being read from the drive. When the extension was removed, and the drive plugged directly into the USB port it worked as expected. The drive was recognized, but when access was attempted ( more current used ) it stopped responding. I have seen that same occurance with a Western Digital Passport USB drive plugged into an extension cable to a USB port. It appears they changed their opinion based on plugging it into another device and it showing up. The problem will come when they try to burn a disk with it. So they plugged it in, and it showed up as a device. I specialized in destructive testing where we tested units/components to their limits, many times breaking them.
Test engineering is something I did at a defense contractor for over 10 years.
Don't worry, I take nothing personal, though I do tend to look at things professionally.
