I have several friends that worked at Seagate when
they had
problems of stiction. It was not a lubricant problem. It was
caused by the surfaces being too smooth. When to really
smooth surfaces sit together for a long time, the air is squeezed
out. Once the surfaces really touch, there is a thing called
molecular adhesion.
Anyone that has worked with guage blocks is familair with
this.
That's the story that I got from the Seagate marketing engineer when
I complained about new ST-225's occasionally showing this problem. .
However, Wikipedia states that the problem really is heat and
lubricants:

So, the moral is "never trust a marketing guy", I guess.
