For those of us who have been using personal computers for the past 20 or so years, defragmenting your hard drive used to just be part of life. When you defrag a hard drive, you're basically re-organizing the data on it so that it will run faster and more efficiently.

When your hard drive stores data, it puts it anywhere there is space available, so it may sometimes put pieces of the same file in several different places instead of right next to each other. Imagine opening a file cabinet and just throwing paperwork into it. You would never be able to find anything if you did that, but your computer can keep track of where it put things even if they are all over the place. This works well, but things can become really messy after a while. This will make the computer start to run slow as it searches through your data. Running a defrag will reorganize everything.

When we received your question, Neila, we realized that we couldn't even remember the last time we defragged a computer. Beginning with Windows 7, Microsoft has built automatic defragmentation into the Windows operating system, so you don't have to worry about running it yourself. However, you can still run it manually if you want. On Windows Vista or 7, look for a program called Disk Defragmenter. On Windows 8, it is called Optimize Drive; you can find it by pressing the Start button on your keyboarding and typing in 'optimize drive.'

Apple has built similar automatic defragmentation into Mac OS X, but that operating system doesn't offer you a manual way to optimize your hard drive. There are third-party defrag programs available, but we don't recommend them because they often cause more problems than they fix. If your Mac is running slow, you should try restarting it and clearing off space on your hard drive instead.

One last note: if you have a Solid State Drive (SSD) instead of a classic hard drive, we don't recommend performing a defrag. It doesn't provide any real benefit on an SSD, and it can actually reduce the drive's lifespan.

In time as you use your Windows machine for different tasks, it would also suffer some serious problems and one of them is the overall decrease in speed and performance. While the cause of this problem is varied, the most common one is the cluttered files that are stored in your hard drive.

This is true especially if your computer is protected with a good antivirus software and is also well maintained in many other aspects but you still notice a significant slowing down in terms of its performance.

What’s the Solution?

Fixing this problem as soon as the earliest sign appears is very important so that further complications can be prevented and thankfully, Microsoft has developed a tool that will help you rearrange everything in your hard drive and organize all the clutter that can come as a result of everyday computer usage.

This tool is called “Disk Defragmenter” back in Window 7 but in Windows 8 and Windows 8.1, it has been given a new name which is “Optimize Drives”. It has also some improvements in its inner-workings and the process has some changes compared to how it was done back in Windows 7but don’t worry because we will be demonstrating the whole process in this tutorial series but before anything else let’s first learn the different ways in launching the “Optimize Drives” tool in your Windows 8.1 machine.

When to Defragment Your Hard Drive

If your computer is running just fine then there is no need to optimize it or run the disk defragment tool however, if you see that there is a significant decrease in its performance then that’s the time that the disk defragment or the “Optimize Drives” tool should be run.

The slowing down is mainly caused by the disorganized packets of data that comes as a result of the repeated reading and writing process whenever you do several tasks on your computer. This happens especially on hard disk drives or HDDs. Defragmenting arranges all of these cluttered data into organized locations with all the related ones grouped together. This would then minimize the time that is required to read and write files as well as accessing them and eventually result to a faster Windows machine.


If your computer is using SSD or Solid State Drive, there would be no need for you to use the defragmenting tool that is built in with Windows. The same thing also applies to USB flash drives. Both SSDs and USB flash drives work differently in terms of allocating space for related data and other files. Both also have limited number of read and write process cycles before they stop working so defragmenting them would result to a decreased lifespan. Given the fast working speeds of SSDs and USB flash drives, there would be no need to run a disk defragment drive on it anyway.
