Recover data from external hard drive
External hard drives are important storage devices for users who use computer for everything. It’s easy to get one external hard disk with large capacity. Users would like to store all kinds of files on it as backup or extra storage space.
However, there are many causes that can lead to data loss issue to external disks. One of the most common one is file deleting and formatting by accident. Many users lose data due to unintentionally operations. The good news is that no matter what the cause, most lost files are recoverable. You can follow steps talked about in this page to do external hard drive recovery.
Why recovering lost data from external hard drive is possible?
When you delete a file or format a disk, data is not really erase. To make clear reason, you should know what happens when you delete data or format hard drive.
Operating system keeps tracks of file location on hard drive via pointers and each file or folder has a pointer which is responsible for telling system where and how your file is stored on disk. When a file gets deleted, operating system only removes the pointer and tags sectors which contain the file as Free. Thus, the deleted file is no longer displayed in Windows Explorer and you get more free disk space to store new data. When system stores new data to those sectors containing the deleted file, the file will be permanently overwritten and no longer recoverable. File recovery software can scan free disk space on the disk and restore deleted files.
Disk formatting works similarly. When you quick format an external hard drive or other device, files and partitions are not immediately erased. The formatting process only clear the index of the items stored on the disk without removing read data. Therefore, your files remain intact on the disk until they get overwritten. That is to say, you have good chance to get formatted files back as long as no data overwriting occurs.
