Why need to defrag hard disk Windows 7?

Maybe you know that too many installed programs on the disk will cause the low performance of your disk, or insufficient disk space may cause your computer to freeze.

But, do you know disk fragmentation? Do you know that disk fragmentation will not only slow down the system but will also accelerate the physical life of the hard disk and form more bad sectors? Accelerate the physical life?

1. Where does disk fragment come from?

In theory, the files should be arranged compactly without gaps and arranged in order of storage time. When you need to boot a program, the disk component will seek all relevant files on the whole disk.

However, the working principle of HDD makes it only arrange files discontinuously and disorderly. The meanwhile, users often modify the file, and the new content isn't added directly to the location of the original file, but the file will be scattered and saved to different places on the disk.

These scattered files are called fragments.

Storage ways

2. How does fragment affect PC/disk performance?

Since the scattered files are continuously stored in contiguous clusters on the disk, the system will add a contact mark between the two segments.

Too many fragments are generated, and other discontinuous files increase accordingly. When the system is performing file operations, the reading efficiency is greatly reduced due to the repeated search for contact files.

The intuitive reflection that follows is the system response delay, then the results are the blue screen of death, file loss, and damage, or important data that cannot be repaired

3. What does defragment do?

The disk defragmentation program is to put a large number of scattered files at the end of the disk and then write them into the files associated with it. In the end, there are no scattered files on the disk.

This procedure is to rearrange scattered files to decrease searching time. Therefore, the performance of the hard drive will be better, and frequent cleaning of disk fragments will also keep the hard disk in good condition and prolong its service life.

How to defragment hard disk in Windows 7?

Since defragmentation is a good method to maintain the disk, in this part, we'll show how to defrag a hard disk in Windows 7 with Windows tools and introduce you to a free defrag tool.

Defragment via 2 Windows tools

Step 3. And you can click "Configure schedule" to set a schedule to automatically run the defragmenter regularly.

Step 4. Then choose the frequency, day, time, and disks. Click "OK" to confirm.

Schedule

Disk Defragmenter allows users to defrag their disks by themselves, but this process may need a few hours, and it can't be interrupted. The best way to run this tool is to let it run alone.

2. Defrag by CMD

Step 1. Click "All Programs" and then "Accessories", right-click "Command Prompt" and choose "Run as administrator".

Step 2. Type defrag /? to check to defrag command lines.

/B: Optimizes boot files and applications but doesn't defragment the rest of the volume.

/C: Defragment all local volumes.

/E: Defragment all local volumes except those specified.

/A: Analyze the volume and display a report, but do not defragment.

/X: Perform free space consolidation.

/T: Track defragmentation already in progress.

/H: Run the defragmentation at normal priority (by default, runs at low priority).

/M: Defragment multiple volumes simultaneously in parallel.

/U: Print the defragmentation process on the screen.

/V: Use verbose mode, which provides additional detailed information.

Choose the operation you want to run, and input the following order:

defrag [drive name] /Command Letter

For example, we run an analysis of the C drive, so we input defrag C: /A

analyze C drive

The disadvantage of CMD to defrag drive is obvious—the command letters. You may input the wrong letter to run a different execution.
