Why MKV Files Disappear
MKV videos can be lost due to accidental deletion, emptying the Recycle Bin, or a quick format that only removes the directory index.
Because the data remains on the drive until overwritten, recovery is often possible.
Immediate Steps: Protect the Drive
- Stop using the drive immediately to prevent overwriting the missing video.
- Do not install or copy new files to the affected disk.
- Connect the drive to a computer where RecoverHelper is installed.
Choose the Right Scan Mode
For MKV files, the Deep Scan is recommended. It first runs a Quick Scan to recover any remaining file‑system entries, then carves the entire drive by signature to find videos that the file system has forgotten.
If the drive is a non‑NTFS volume (e.g., SD card or USB), you can also use Carving Only to focus on signature recovery.
Recovering Your Videos Safely
- Run the selected scan mode and preview the found MKV files.
- Select the videos you need.
- Save (recover) them **to a different drive** – RecoverHelper blocks same‑drive output to protect your source data.
