This > bug is confirmed there. Yup. Last I heard, Tejun has fixed this, and queued the code for 2.6.22 via James B. But this could be considered a rather nasty regression in 2.6.21, in that it does seem to cause significant and unnecessary wear and tear on the drive mechanisms. I'll patch it locally on my own machines, but what about the tens of thousands of other Seagate notebook drive owners out there?
