His solution was to put CM7 on the internal memory, and that is what I like as well. If you want to continue with an SD card you might try formating the SD card with SD Formatter from SDcard.org. That will ensure that you have a properly formatted and clean SD card to start you install with.

BTW, CM7 is Honeycomb.
