Recovering data from a damaged external hard disk can be a complex process, and the specific method depends on the nature of the damage. Here are some common situations and corresponding recovery methods:
Logical Damage
File System Errors
Use Built-in Tools: For Windows systems, you can use the CHKDSK command. Open the Command Prompt as an administrator and enter “chkdsk X: /f” (replace X with the drive letter of the external hard disk). This command checks the file system for errors and attempts to repair them. On a Mac, the Disk Utility can be used to verify and repair the disk. Open Disk Utility, select the external hard disk, and click “First Aid”.

Accidental Deletion or Formatting
Stop Using the Disk Immediately: To prevent new data from overwriting the deleted or formatted data, stop using the external hard disk as soon as possible.
Use Data Recovery Software: The same third-party software mentioned above can be used for this situation. They have features to recover deleted or formatted files by scanning the disk for 残留 data.
Physical Damage
External Physical Damage
Inspect the Cable and Connector: Check if the cable and connector of the external hard disk are damaged. If so, try replacing them with a new cable or connector to see if the hard disk can be recognized.
Check the Power Supply: If the external hard disk requires an external power supply, make sure the power adapter is working properly. Test it with a multimeter or try using a different power adapter.
Internal Physical Damage
Do Not Attempt DIY Repair: If the hard disk makes unusual noises, such as clicking or grinding sounds, or if there is suspected damage to the internal components, it is best to avoid opening the hard disk yourself. The internal components of the hard disk are very delicate and any incorrect operation can cause further damage.
Seek Professional Data Recovery Services: Professional data recovery companies have specialized equipment and technicians to handle internal physical damage. They can open the hard disk in a clean room environment and attempt to recover the data. Some well-known data recovery companies include DriveSavers and Gillware.
Other Considerations
Regular Backup: The best way to prevent data loss is to have regular backups of your important data. You can use cloud storage services like Google Drive or Dropbox, or an external hard disk for backup.
Data Recovery Precautions: When using data recovery software, make sure to download it from a trusted source to avoid downloading malware. Also, be cautious when using free versions of data recovery software, as they may have limitations or display ads.
In conclusion, data recovery from a damaged external hard disk requires a careful approach. For logical damage, you can try using built-in tools or third-party software. For physical damage, it is often best to seek professional help. And remember, prevention is always better than cure, so regular backups are essential to protect your valuable data.
