03 By Redownloading the MKV Video

If you've downloaded an MKV video from the internet, there's a chance it may not have been fully downloaded, resulting in a broken, corrupted, or damaged file. This can happen when there's an accidental process termination during the download.

To avoid damaged, broken, or corrupted MKV files, it's best to re-download the source file with a compatible MKV codec. Another option is to use media players with built-in MKV-compatible codecs, such as VLC or Leawo Blu-ray Player.

Alternatively, you can search for compatible codecs online and add them to your current player tool, such as Windows Media Player, to support unplayable MKV video files.



CHKDSK is also an effective tool for scanning storage devices and preventing MKV file corruption. It scans the device and identifies any bad sector issues, allowing you to repair the problem and restore your storage media to working order.

To repair damaged MKV files using CHKDSK, follow these simple steps:

Step 1: Open the Command Prompt window. Ensure that the corrupted drive is connected to the system.

Step 2: Assign a new letter to the corrupt drive. And type chkdsk /r /f X: (where X is the new drive letter) and press the Enter key.


Step 3: Wait for the process to finish, then restart your system to check whether the drive is accessible.

By following these steps, you can effectively repair any corrupt MKV files on your storage media and ensure that your files remain safe and accessible.

05 By Converting File to Another Format

Converting a corrupted MKV file to another format is another method that can be used to repair the file. This method works by re-encoding the corrupted file into a new format that is free of errors. The process involves using a video converter tool to convert the MKV file to another format such as MP4, AVI, or MOV.
