I was correct: "What are the backward compatibility characteristics of the Ultrium format? The LTO Ultrium compatibility is defined with two concepts demonstrating investment protection: 1) An Ultrium drive can read data from a cartridge in its own generation and two prior generations. 2) An Ultrium drive can write data to a cartridge in its own generation and to a cartridge from the immediate prior generation in the prior generation format.
