How to Recover Lost Files After Defragmentation
We sometimes hear people discussing computer fragmentation and how fragmentation slows down your computer. So, what is the fragmentation exactly and what is the significance of defragmentation?
What is Fragmentation?
Fragmentation is the result of how file systems handle data. Some operating system’s file system, like NTFS and FAT32, tends to allocate contents of files in non-contiguous clusters for future in-place modification. Also, when you save your data and files, your computer finds any available space on your hard drive and stores the information. For example, the storage space of a deleted old file will be marked as available and will be overwritten by new files when needed. These separated pieces of data scattering around the drive storage medium are generally called “fragments”.
Why does fragmentation slow down a computer?
File fragments can happen to hard disk drives (HDD), as well as solid-state drives (SSD). But the negative consequences on HDD are more significant due to its electromechanical nature. To read a file, the HDD read/write head will have to search the whole disk to locate and access each and every fragment. This will take up time and energy, slowing down programs and operating system functions.
What is Defragmentation
Defragmentation is the process of physically reorganizing files into fewer fragments. When you defrag your hard drive, you are putting these pieces back together and clearing the scattered file clusters. This process organizes and rearranges your hard drive and makes the bits of data easier for your computer to find.
When you defrag your computer you not only gain increase speed but also extend the hardware lifespan. The mechanical parts of the drive have to travel less distance when the data is all in one place, thereby reducing wear and tear on the drive itself.
One of the biggest reasons for defragging your hard drive is faster speeds and less loading time. Programs run faster and more efficiently when the data is grouped together for easier access. Defrag also clears up all unused space and gives you more available space for storing files. When you defrag your computer you not only gain increase speed but also extend the hardware lifespan. The mechanical parts of the drive have to travel less distance when the data is all in one place, thereby reducing wear and tear on the drive itself.
How to Recover Files that Are Missing After Defragmentation
Normally, you don’t have to worry about files getting deleted by defragmentation process. But if the defragmentation process is inappropriately ended because of, for example, sudden power outage, some files may end up missing.
If you find files get accidentally deleted during the defragmentation process, you can try to locate and retrieve missing files by using a professional data recovery software. Here we recommend H Data Recovery Software. H Data Recovery Software offers 6 unique data recovery modules, each is designed to handle different data loss situations. For accidental deletion, select the Accidental Deletion Recovery module. After the scan, you can choose from the list of files that the software successfully found, and restore them to a safe destination of your choice. Alternatively, you can also choose the Universal Recovery module for a more thorough and complete data scan. It may take some time to complete, depending on your storage size, because this feature attempts to scan and locate every deleted file on all detected hard drives.
