I've seen this happen most frequently on hot-running drives (such
as the barracudas and those 2GB HVD SCSI that HP used in their '700
hundred series in the early 90's--I forget the model, C2490? ).
Thus, it makes sense that the failure mode was that of the
grease going hard; this should be specially frequent at
higher temperatures.

I've had quite a few ST410800 (WD, N and W suffixes) 5.25" drives up
and running continuously for >5 years in a variety of machines, though.
They are incredibly reliable.
