From everything I've heard, RK07s were ... subpar. I'm not surprised one failed like that. RL02s were meh, but they worked, the first system I was responsible for had 1 or 2 of them. I asked because the RA81 which was released in 1982 was, in MIT's Project Athena experience, awful, they had some sort of problem with glue, and they were losing 1 a week out of a population of no more than 40 drives (!). But it sounds like they were more careful, more lucky, whatever with the earlier RM80s, which I don't remember hearing anything bad about.
