You can refer to the color codes on the program and the following descriptions of the codes to better understand the status:
• Red
This means most of the clusters are part of a frag-mented file
• Blue
This means most of the clusters are contiguous files with clusters in the group that contain only free space and contiguous clusters
• Green
This means most of the clusters are part of a file that cannot be moved from its current location
• White
This means most of the clusters are free space and contiguous clusters
4. At the end of the analysis, a pop-up message will appear,
as Figure 6-28 shows This lets you know it has completed and if you should continue with the defragmentation
Figure 6-28 shows an example of when a defragmentation
is not recommended

From this point you can do one of the following:
• View a report for more details about your current fragmentation status
You can simply click the View Report button, as shown in Figure 6-29
Figure 6-29: Accessing the fragmentation report
You will then see the Analysis Report window, such as shown in Figure 6-30, which shows detailed information about the hard drive (or volume) that was scanned

Trang 4You can get a good indicator of the hard drive (or volume) fragmentation state by referring to your average number of fragments per file As Figure 6-31 shows, this piece of information is located in the Volume Information list
Figure 6-31: Example of average number of fragments per file
You can then compare your number to the following aver-age number of fragments per file ranges, which gives you
an idea of how bad your fragmentation is at the time:
• 1.00
Most or all files are contiguous
• 1.10
About 10% of the files are in fragments of two or more pieces
• 1.20
About 20% of the files are in fragments of two or more pieces
• 1.30
About 30% of the files are in fragments of two or more pieces
• 2.00
Most or all of the files are in fragments of two or more pieces

Trang 5• Continue with the defragmentation
Simply click the Defragment button, as Figure 6-32 shows,
to begin the defragmentation, and then continue with Step
3 on the next set of steps
Figure 6-32: Starting the defragmentation
• Close the window
To close the pop-up window, for example if it recommends not performing a defragmentation, you can click Close, as seen in Figure 6-33
Figure 6-33: Closing the pop-up status message
Here is how to defragment your hard drive using Windows XP:
1. Open Disk Defragmenter, which can be accessed by brows-ing to the followbrows-ing path on your Start menu:
• Start
• Programs (or All Programs)
• Accessories
• System Tools Then click Disk Defragmenter, as shown in Figure 6-34
2. Click Defragment, as shown in Figure 6-35
The amount of time that defragmentation takes, which can take up to several hours, depends on several factors includ-ing the followinclud-ing:
• Amount of fragmentation
• Size of the hard drive
