The typical recovery process involves launching the software, selecting the external hard drive as the target, running a scan to detect deleted files, and then previewing and restoring the desired files to a different storage location to avoid data overwriting.

Manual Methods for Recovering Deleted Files

In some cases, manual methods may assist in recovering deleted files without the need for additional software. These methods are generally suitable if the deletion was recent and no new data has overwritten the deleted file space.

One common approach is checking the Recycle Bin or Trash folder on your computer. Although external hard drives generally do not have a recycle bin, if the deletion occurred while the drive was connected, the files might have been moved there temporarily.

Another manual method involves using built-in system utilities:

  • Windows File History: If enabled, this feature allows users to restore previous versions of files and folders.
  • macOS Time Machine: A backup system that can retrieve older versions of files stored on external drives.
  • Command Prompt or Terminal: Advanced users can attempt to use command-line tools like `chkdsk` on Windows or `fsck` on macOS/Linux to fix file system errors that might recover lost files.

It’s important to note that these manual methods rely on prior system configurations like backups or versioning and may not work if such setups were not in place.

Preventative Measures to Avoid Future Data Loss

After successfully recovering deleted files, implementing preventative strategies is crucial to minimize the risk of future data loss. These measures include:

  • Regular Backups: Maintain periodic backups of important data using cloud services or separate storage devices.
  • Safe Ejection: Always properly eject external drives before disconnecting to avoid corruption.
  • Use of Reliable Hardware: Invest in high-quality external hard drives with good reviews and warranties.
  • Antivirus Protection: Keep antivirus software up to date to prevent malware that may delete or corrupt files.
  • Enable File Versioning: Use system features or third-party tools that keep versions of files to allow easy restoration.

Adopting these practices helps ensure data integrity and provides multiple recovery points, reducing dependence on complex recovery operations.
