That's a great article. So to answer the question in the summary, the way to verify your firmware is:
Buy an identical replacement drive
Use the vendor tool to install the same firmware version
Use the tool described in the article to read the firmware from each drive over JTAG
Compare the two copies to see if the suspect drive has been modified.
