While it seems pathological, I'd leave it alone if the drive is being
used for the proper workload it was designed for. The less time the
heads are flying over platter surface, the better. Even though this
attribute value is 001 and the threshold is 000, it's not a pre-fail
attribute, just an age attribute. It's probably instigated at least as
much by something that's fsyncing every ~90 seconds like the journal
or rsyslog.
