Part 1: What Makes FLV Files Corrupted?

There can be many reasons behind a corrupted FLV file. We tend to delete some of the important data without thinking much. Some instances are unintentional, while others aren’t. No matter we you delete the data, we find ways to retrieve them if they are so important.

However, some of the data recovery apps we use can recover files poorly. Unless you use a powerful data recovery tool like Wondershare data recovery, the outcome might be poor. This is particularly true when it comes to video files. Recovered video files often get crashed due to corruption. They fail to play on video players no matter how hard you try.

Here are some of the most common reasons that can contribute to a corrupted video file. Mentioned below are those reasons for your information.

Error Writing or Reading Data

When we start to edit a file, the respective file’s internal architecture will be rewritten. This is required to apply the changes we make to the respective file. However, if the file is closed unexpectedly during this process, serious issues can occur. As a result, your file is most likely to experience issues pertaining to missing information or poor structure.

Damaged or Lost Information

As of today, we all tend to transfer information very often due to various reasons. Thanks to modern-day technology, we have a wide array of options to transfer files through different media. Some of those media are physical, and others are not.

• Transferring Data through the Internet

We can transfer data through email, cloud storage, etc. Despite the convenience of these methods, they are prone to lose information due to internet failure or poor connection. As long as the connection is not stable enough to transfer data to servers, transferring issues can appear. Also, the smooth transferring of data can be prevented by malware infections. Regardless of the cause, if the transfer is interrupted, the respective file will be damaged.

• Data Transfer through Physical Devices

USB Flash drives, external hard drives, DVDs, SSD, etc. As you can understand, physical media are prone to physical damage. For instance, they can malfunction due to power failures, crashes, impacts, heat, etc. As a result, the information present in them can get damaged, causing writing and reading errors.
