Easy setup lets Win2000 achieve optimal performance

5. When the defragmentation process is complete, select the next volume to defragment (if there are other volumes) until all the volumes have been defragmented and merged.
Understanding color code Display diagrams
Disk Defragmenter uses a color code system to display the organization of different file types and free space in a volume. Fragmented files are red, contiguous files are blue, system files (including MFT and paging files) are green, and free space is white. The size of each color block on the display diagram represents how much space each file element occupies in the volume and its relative position.
It is important to understand the "approximate" status of the disk represented by the color code map. In fact, each image pixel (72 pixels = 1 English) typically represents thousands of clusters, some of which may be mixed with fragmented files, contiguous files, free space, and system files. With this in mind, the algorithm determines what color to display according to the main specific file elements that make up the disk sector (represented by each image pixel). In addition, Disk Defragmenter displays a slightly skewed disk condition because it is approximate.
For example, if the displayed image pixel represents 1000 clusters, where 51% is contiguous and 49% is free, Disk Defragmenter displays the segment as a continuous blue. The result hides the free space and the total amount of free space on the display appears to be much smaller than the actual number reported by Windows Explorer. However, after the disk defragmentation succeeds, the color display will show more accurate disk conditions and more accurate representation of the available space.
Defragmentation requires enough space on the disk
If the fragmentation of the disk that you want to defragment is already very serious, there may not be enough space on the disk to run the defragmentation process. This is because before the original cluster is marked as available, a full backup of the defragmented file is made at the new location after defragmentation.
After disk defragmentation, Disk Defragmenter may still report: "It is recommended" and "Defragment this disk." (It is recommended that you defragment this disk.) This indicates that there is too little free space on the disk to effectively perform the defragmenter. At this point, you should do the following:
Temporarily delete some large files from the disk.
. delete files that are no longer needed.
Calculate the amount of free space required
As described above, 1/8 of the disk is allocated to the MFT zone in the sector that describes the primary file table. Although this area is marked as free space, it is reserved only for the MFT dedicated by Windows 2000. When defragmenting, Disk Defragmenter cannot move files to the MFT zone to take advantage of the space. Therefore, when calculating the total free space for defragmentation, you must subtract 12% from the free space reported by Windows Explorer. It is recommended that you keep an NTFS-formatted disk with 30% free space to ensure that there is sufficient space for effective defragmentation.
Summarize
File fragmentation can adversely affect the speed and performance of the operating system. To maintain the best performance when using Windows 2000, you should periodically analyze the disk status (preferably once a week for moderate and heavy use, and reduce frequency for intermittent usage) and defragment as needed.
Disk Defragmenter is used primarily for stand-alone and users with administrator privileges, and not for network defragmentation. Administrators who require network control, automatic scheduling, and defragmentation at the same time for multiple partitions and MFT and paging files should consider upgrading to a third-party defragmenter that can be performed on the network.
