Recovering Deleted Files from Flash Drives: A Guide to Handling Unexpected Data Loss
Data loss can be a frustrating experience, especially when it occurs unexpectedly and without clear explanation. Recently, users have reported incidents where files on USB flash drives seem to vanish on their own, leading to confusion and concern over potential data corruption or hardware issues. In this article, we will explore common causes of such problems, troubleshooting steps to recover lost data, and best practices to prevent future incidents.
Understanding The Issue
Imagine connecting your trusted USB flash drive to transfer photos or documents, only to find that some folders have disappeared without any direct action on your part. For instance, a user reported that their PNY Duo Link USB drive, used in conjunction with an iPhone, suddenly lost two folders—one missing after a mass file deletion, and another added just a day prior, which mysteriously vanished. These situations can be distressing, especially when the user is uncertain whether they accidentally deleted the files or if other factors are at play.

- Malicious Software or Malware: Certain malware can delete or hide files on storage devices.
