Hi, I have cloned my iBook several times for various reasons, and I am now considering to do a fresh install of OS X Tiger since it seems as though my computer has slowed down a bit and is doing some odd things, like automatically ejecting my iPod and not ejecting my external drive when I tell it to. Does anyone know if repeated cloning has any negative effects on a system? Or is it just in my head? Or maybe should I just go buy a MacBook already? Thanks!
