Recovering erased files from an external hard drive is a challenge many users face, especially when critical data such as work documents, photos, or videos seem permanently lost. Fortunately, deleted files are not always gone forever. When a file is erased, the actual data remains on the disk until overwritten by new data.
When you delete a file from an external hard drive, it does not immediately disappear. Instead, the operating system marks the space occupied by the file as available for reuse. Until new data overwrites this space, the file’s content remains intact and potentially recoverable.
Why Files Get Erased or Lost
Accidental deletion: Users often delete files unintentionally.
Formatting: Formatting a drive erases its index, making files inaccessible.
Corruption: File system corruption due to improper ejection, power failure, or malware.
Virus or malware attacks: Malicious programs can delete or encrypt files.
Drive failure: Hardware issues can lead to inaccessible or lost files.
Partition loss: Partition deletion or resizing can hide files.
Preparing for Data Recovery
Important Precautions
Stop using the external hard drive immediately: Further use risks overwriting deleted data.
Do not install recovery software on the same drive: Install recovery tools on your internal drive or another external drive.
Avoid formatting the drive unless as a last resort: Formatting can complicate recovery but sometimes is necessary for deeper scans.
Step 1: Basic Checks and Access
Check Recycle Bin/Trash: Sometimes deleted files remain here.
Connect the drive properly: Use a different USB port or cable if the drive isn’t recognized.
Try another computer: This rules out system-specific issues.
Check drive health: Use tools like CrystalDiskInfo to assess hardware status.
Step 2: Use Built-in System Tools
Windows: File History and Previous Versions
Right-click the folder where the file was located.
Select Properties > Previous Versions tab.
Restore from available snapshots.
Mac: Time Machine
Use Time Machine to restore deleted files if backups exist.
