1. Symptoms of a Failing or Broken External Hard Drive
Before attempting recovery, identify the symptoms of your external hard drive failure. These can help determine whether the problem is related to hardware, software, or file corruption.
a. The External Drive Is Not Recognized
• The drive does not appear in File Explorer (Windows) or Finder (Mac).
• It appears in Disk Management (Windows) or Disk Utility (Mac) but as “RAW” or “Unallocated.”
b. Clicking or Grinding Noises
• If the drive makes unusual clicking, beeping, or grinding sounds, it likely has physical damage.
c. Slow Performance or Freezing
• The drive slows down the computer or causes system crashes.
d. Corrupt or Missing Files
• Files have turned into unreadable symbols or disappeared entirely.
• Error messages like “The file or directory is corrupted and unreadable.”
e. Frequent Disconnections
• The external hard drive keeps disconnecting on its own.
• Windows or macOS prompts you to format the drive.
If you experience any of these issues, follow the recovery methods below before assuming your data is lost.
2. How to Recover Data from a Broken External Hard Drive
a. Check Hardware Issues First
Before using any software, test for simple issues:
