When I run defrag lately, afterwards it always says there are 3 MFT fragments left. I defrag on a regular basis. Previously, defrag always did the job completely (except for a brief time a few months ago, after which it returned to normal functioning w/o my knowing the cause or the cure). Does anyone know what might cause this slightly incomplete defragging, and if it matters? I've spent hours reading stuff found in Google search, and I'm no closer to an answer than I was at the outset; nothing I read sounds like what's happening here. I've got WinXPH/SP1 in a Dell2350.
