Re: Defragging
Google on Defrag:
"Defraging" a hard drive simply optimizes or organizes the placement of files on the physical surface of the drive itself. In the course of using your machine your system writes data to the HDD, your computer automatically writes your data to the first available spot on your HDD. As the days and months pass your HDD will tend to get very "messy" or fragmented.
A fragmented HDD takes a little more time to read then a defragmented drive. Your HDD will have to grab some data from one part of the disk then grab some other data from another part. In a nutshell your HDD becomes disorganized and the HDD has a rough time finding things easily, this ultimately causes your machine to run slower.
When a "defrag" program is run it really just puts the pieces back together, and organizes your HDD so that your data loads faster. It's generally considered a good idea for the average user to defrag once every 3 months or so.
