Step 9Disk Defragmenter
iImage Information

Windows Disk Defragmenter is a computer program included in Microsoft Windows, designed to increase access speed (and sometimes increase the amount of usable space) by rearranging files stored on a disk to occupy contiguous storage locations, or defragmenting. The purpose is to optimize the time it takes to read and write files to/from the disk by minimizing head travel time and maximizing the transfer rate.

You normally want to run this at night before you go to bed. Let it run while you sleep, and then restart your computer when it's finished.
NEVER defrag an SSD. I have 6 of these. The manufacturer states that the flash technology will access any data in any location at the same speed. Repeatedly writing data (as happens in defrag movements) will decrease the life expectancy of the solid state itself.
I believe this step should be removed due to the PROBABILITY of readers misapplying the instructions to the wrong media. It should only be for PATA drives.
