That would be it; amazing how quiet the bugger is. I would totally put it in any fanless-or-otherwise-quiet PowerBook, just to complete the silenceYep, I have the same drive in my 1400, though a Hitachi unit (I'm assuming that yours is the 4200 rpm version as mine is), and its quieter than a cat burglar. Good choice of drive for a 1400, IMHOJust an FYI, the 30 gig that I yanked from the Vaio is an IBM Travelstar, and it's deathly silent. Unless it's reading or writing, you'd think this thing had an SSD in it. Add that with the fan never coming on, and you have an epic writing machine or just overall very quiet laptop
