Slow performance in my MacBook 13'' Early 2009. Run out of disk space.
Smooth. Simple. Upgrading memory and Hard Drive are among the easiest task you can do in this MacBook model.
Before taking out the Hard Drive, I repaired permissions. I used the rubber case included in the kit to be able to use the old HD as external backup, then I restored data from old HD to new Flash Drive using Mavericks and recovery utility included in the OS.
