Hey all, A few weeks back I had to swap out my Samsung XT disk for the HD that came with the MBP. This was required by a client as they needed a fresh install of OSX, specialised tools and also whole disk encryption. Once I had finished the project, I simply swapped the XT disk back in. I have noticed that the startup times reaaaaaally drag, and I'm getting the beach ball a lot more than I used to just doing day-day stuff. Having just read something about resetting PRAM etc - would using another disk, different software and enabling disk encryption require this to be done? Is it worth a try anyway? Can anyone think of any other reasons/fixes?
