Recovering Lost Files from an SD Card: A Case Study in Data Recovery with DMDE
Data loss during file transfer processes can be a stressful experience, especially when important videos or documents are involved. Recently, a user encountered an issue while moving files from an SD card to an external hard drive, which resulted in missing files despite the transfer seemingly being near completion. In this article, we will explore this scenario, discuss the potential causes, and provide guidance on using DMDE, a powerful data recovery tool, to retrieve lost files.
The Scenario: Interrupted File Transfer
The user attempted to relocate video files from an SD card to an external hard drive. During the transfer, a notification appeared indicating that some files were no longer at the source location, implying that the cut operation had failed or partially completed. Subsequently, some files vanished from the SD card, and attempts to eject the drive were unresponsive. After restarting the computer and rechecking, the files remained missing from both the SD card and the intended destination.
Initial Troubleshooting Steps
In such situations, it’s crucial to avoid further writing to affected storage devices, as this can diminish the chances of successful recovery. The user wisely refrained from additional transfers and worked on recovering the files.
Data Recovery Efforts with DMDE
DMDE (DM Disk Editor and Data Recovery Software) is a robust tool favored for its effectiveness in recovering lost or deleted files from various storage devices.
Key steps taken:
-
Partial Recovery of Files: The user managed to recover some files (notably those named C0100 to C0115), indicating that DMDE could detect portions of the volume or file remnants.
-
Incomplete File Listing: Other files did not appear in DMDE’s folder view, and full volume scans did not reveal them by name. This raises questions about whether these files were overwritten, renamed, or irretrievably lost.
Understanding Why Files May Be Missing or Unrecoverable
There are several reasons why certain files might not be recoverable or visible:
-
File Overwriting: If new data was written to the SD card after the transfer failure, original files might have been overwritten.
-
File System Damage: Interruptions during file transfer can corrupt the file system, complicating recovery.
-
File Name Changes or Loss: Recovered files may have different names, or the filenames might be lost during corruption.
-
Incomplete or Partial Data: Files not fully transferred might be incomplete,
