How to recover data from damaged external hard disk？

To recover data from a damaged external hard disk, it is essential to follow a structured approach, ensuring both the safety of the disk and your data.

1. Symptoms of a Damaged External Hard Drive

Before diving into the recovery process, it’s crucial to identify the specific symptoms of damage to your external hard disk. Some common indicators that your external hard drive may be damaged include:

Drive not being detected by the computer: When you plug in the external hard drive, it is not recognized by your computer, and no drive letter is assigned.

Strange noises: Clicking, grinding, or beeping sounds coming from the drive are signs of mechanical failure.

Slow performance: The drive becomes unresponsive or extremely slow to access or transfer files.

Corrupted or missing files: Files appear as corrupted, or you might experience errors when attempting to access them.

Blue screen or crash: The operating system crashes or freezes when the drive is connected.

2. Safety First: Avoid Further Damage

When an external hard drive becomes damaged, it is essential to minimize the risk of further damage to the device and your data. Here’s what you should avoid:

Do not attempt to open the hard drive: This can expose the delicate internal components to dust and debris, which may worsen the damage.

Avoid frequent plugging and unplugging: Repeated attempts to connect and disconnect the drive can cause additional harm to both the drive and the computer’s USB port.

Do not attempt quick fixes or force recovery: If you hear unusual noises or notice any signs of mechanical failure, forcing the drive to work might damage it permanently.

3. Initial Diagnostic Steps

Before performing any recovery operations, conduct the following checks:

Check the cables and port: Ensure the USB or power cable is not damaged and that the USB port is functioning properly. Sometimes, faulty cables or connections can lead to issues with the drive.

Try a different computer: Connect the external hard drive to another computer or laptop to see if the issue is with the original system.

Listen to the drive: Pay attention to the sounds the drive makes when powered on. Clicking, buzzing, or grinding sounds are typically signs of a mechanical failure, while no sound at all could indicate an issue with the drive’s motor or circuit board.

4. Use Built-In Operating System Tools

Many operating systems come with built-in tools to diagnose and repair external hard drive issues. Here are some options:

For Windows:

Disk Management: Open Disk Management by typing disk management in the Start menu. Check if your external hard drive appears here and whether it has a healthy status.

CHKDSK: Run the chkdsk (Check Disk) utility to attempt automatic repairs on the external drive. Open Command Prompt (CMD) as an administrator and type:

bash

chkdsk X: /f /r

Replace “X” with the drive letter of your external hard disk. This will check for file system errors and attempt to fix them.

For macOS:

Disk Utility: Open Disk Utility and check if your external drive is listed. If it appears but is unmountable, you can use the “First Aid” feature to attempt repairs.

Terminal: For more advanced users, Terminal commands such as fsck can be used to check and repair file systems manually.

6. Performing Data Recovery: Step-by-Step Process

Here’s a general outline for using recovery software to restore your files:

Step 1: Download and Install Data Recovery Software

Choose a reputable data recovery program and install it on your computer. Make sure to install it on a different drive than the one you’re attempting to recover data from to avoid overwriting the data.

Step 2: Connect the External Hard Drive

Connect the damaged external hard drive to your computer via USB. If the drive is not detected, you might need to try a different USB port, cable, or computer.

Step 3: Launch the Software and Select the Damaged Drive

Open the recovery software, and select your external hard drive from the list of available drives. Some software may automatically detect and list the drive.

Step 4: Start the Scan

Most data recovery tools offer two types of scans:

Quick Scan: A faster, less thorough scan that looks for recently deleted files.

Deep Scan: A more thorough scan that examines the entire drive for lost or corrupted files. It may take longer but has a higher chance of recovering data from a damaged or corrupted drive.

Start the scan and wait for it to complete. Depending on the size of the drive and the extent of the damage, the scan may take some time.

Step 5: Preview and Select Files for Recovery

Once the scan is complete, the software will display a list of recoverable files. Most programs allow you to preview the files before recovering them. Carefully go through the files and select those you wish to recover.

Step 6: Recover Files to a Safe Location

It’s essential to recover the files to a different drive than the one you’re recovering from. This ensures you don’t overwrite any remaining data on the damaged drive. Choose a separate folder or location on your computer or another external device.

7. Handling Physical Damage

If your external hard drive has physical damage (e.g., a clicking sound, drive not spinning), the recovery process becomes more complex. In such cases, software solutions may not work, and professional data recovery services might be your best option.

Signs of Physical Damage:

Clicking, grinding, or whirring sounds: Indicate possible mechanical failure.

Drive not spinning up: The motor inside the drive may be damaged.

Burn marks or electrical smell: Indicates a problem with the drive’s circuit board.

9. Preventing Future Data Loss

Once your data is recovered, it’s important to take steps to prevent future data loss:

Create regular backups: Use external drives, cloud services, or network-attached storage (NAS) to back up your important files regularly.

Check the health of your external drive: Use tools like CrystalDiskInfo to monitor the health of your external hard drive and check for any warning signs of failure.

Handle the drive with care: Avoid physical impacts, extreme temperatures, and excessive moisture to protect your external hard disk from damage.
