OHHH! Now that's important information! YES, I am sure it WAS
with old G320 drives, probably over 2 years ago, that people had these
problems! I did not know these were added AFTER the first ones
went into the field. (It would have been nice if Mariss mentioned that
only the later units had these filters in his scathing message yesterday.)
