What is hard disk fragmentation?
The Hard Disk Drive or Hard Disk is a system storage device which stores data in encoded form. The hard disk is divided into different tracks. Each track is divided in different sectors. The data is written and read back by the use of the head arm.
During the process of data storage, the head arm moves through the surface of the hard disk to find suitable space to store complete information in sequential or linear format. When appropriate free space is available, the information is stored in its entirety in space (with no gaps in between).
While the data is read back, the head arm does not have to rotate too many times to locate the complete information. But in the absence of availability of suitable volume of free space, the data is stored in various locations on the hard disk.
In such a scenario, while the information is read back, the head arm has to read the scattered information from various locations rotating more than once. The time taken to read the fragmented data is longer in comparison to accessing the non-fragmented data. This whole process of fragmentation increases the data access time. Consequently, speed and performance are hampered.
What causes fragmentation?
Fragmentation is a phenomenon wherein the data storage is disorganized and unsystematic. In deficiency of (continuous or linear) space to be allocated, the system is unable to store complete information in sequential order. So the system takes more time to read the fragmented data back from the hard disk.
Fragmentation is caused by:
- Less free space available - Whenever sufficient free space is unavailable to store the entire information, the storage is in parts in the hard disk.
- Frequent deletions - Often, the unwanted data is deleted from the hard disk. In this process, free gaps are left in between fragmenting the hard disk.
- Extension of Files - Additions made to the already stored files may not be stored in the same sequence in the hard disk in the absence of enough space. Usually in such case, the system creates an extension of the file and stores it somewhere else.
- Moving of Data - There can be instances when data is moved to a new location and there isn't enough space to store all the data. The information is then stored in pieces on the hard disk.
How Do I Use Defragger?
Step 1: Welcome
On the Welcome screen, you find a drop-down menu under the section "Select Hard Drive" from which a drive has to be selected to initiate scanning.
Following this, you may click on "Start Scan Now" to start the scan on the selected drive.
You may also check mark this option to skip the disk analysis and directly start the defragmentation process for the selected drive. This will directly take you to the fourth step (Optimizing) without showing you the scan results, and defrag the selected disk.
Step 2: Scan
The next step shows the scanning progress of the selected drive. Each drive consists of several sectors. Each sector is analyzed extensively by Defragger Disk Optimizer. The graph shows the actual status of the hard disk, with a legend underneath displaying specifics.
Explanation of terms used in Legend:
* Free - Refers to the space on the hard disk which stores no data and can be used for storage purposes. Disk Optimizer puts together all the scattered chunks of free space in one place on disk.
* Allocated - Refers to the space pre-designated by the system to store important files. Disk Optimizer detects fragments in the allocated space and removes them.
* Defragmented - Refers to the data on the hard disk which is not scattered and is saved in its entirety in one space.
* Fragmented - Refers to the data stored in various locations on the hard disk Using fragmented. Disk Optimizer defragments the data for faster data access.
* MFT - Refers to the Master File Table in which the information of every file and directory is stored with its attributes. It is always good if the MFT is stored in the hard disk in space. The search for any information or file will then be faster. Disk Optimizer defragments the scattered MFT.
* MFT Zone - MFT on the hard disk improves responsiveness and performance. For this the pre-allocated space for MFT is not taken in use during regular storage and the cluster of this space remains non-fragmented. This is referred to as the MFT Zone. When the rest of the hard disk space has been consumed, the MFT Zone is then taken in use. When the MFT is expanded, it also gets fragmented. This becomes a serious area of concern, as there is a direct impact on data access time and system performance. Disk Optimizer identifies fragments in the MFT Zone and removes them.
* Directory - Refers to directories stored on the hard disk space. Directory is where multiple files, folders or information are stored. Disk Optimizer identifies the scattered portions of directories and brings them together.
* Pagefile - Refers to a part of the hard disk wherein data not being used recently in the RAM is stored. A page file is read faster, as it is a chunk of data. The size of the page file can be set by the user as per the requirements. Disk Optimizer will defragment the fragmented page file for faster data access.
* Locked - Refers to those files, folders and applications which are locked or made un-editable by the system to inhibit the user's interference. Some files currently in use cannot be included in the process of defragmentation. Such files are also considered locked. Disk Optimizer will not be able to defragment the locked files.
To stop the process of scanning, you may click on "Stop" button any time during the process.
Step 3: Results
Once the scan is complete, a scan summary is exhibited, showing approximate figures for the volume of hard disk found to be fragmented, the number of non-optimized files found to be fragmented, and the current largest volume of space found on the hard disk. Also, you will be informed whether defragging is needed or not.
Note: Defragging the hard disk is always recommended for better system performance.
On clicking on the "Detailed Report" the disk scanning report can be viewed in detail. The report is web based and can be viewed only when you are connected to the internet.
The data fragmented on the hard disk adversely affects the system's performance. This should be taken care of promptly. Click the "Defrag" button to defragment the data on the disk. This will improve data access time.
On clicking on "Cancel" button, you may move back to the Welcome screen and scan another drive for fragmentation.
Step 4: Optimizing
The moment you click "Defrag", Defragger Disk Optimizer starts the actual process of defragmentation. Small chunks of free space are put together to create a large chunk of free space for better and more efficient data storage. The scattered data is brought together and saved in one space on the disk. This process takes some time to complete.
The process of defragmentation can be stopped anytime during the process by clicking on the "Stop Defrag" button in the lower right corner of the screen.
Step 5: Finish
The last step shows the optimization summary. Disk Scan Summary - The optimization summary for the selected drive is shown in this section. The total number of files which have been defragmented, percentage of data fragmented and percentage of volume defragmented, are exhibited showing what Defragger Disk Optimizer has done to improve the data storage on the hard disk.
Click the "Finish" button to go back to the Welcome screen to start the process of defragmentation for other drives.
