Problem diagnosis – the first step to success

The key to successful data recovery is understanding the cause of the problem. Hard drive failure can occur for a variety of reasons, from human error to mechanical failure. Here are some common causes of hard drive failure:

Human Errors

Accidentally formatting a drive, deleting key files, or writing new data to the drive before creating a backup can lead to the loss of important information. The most common human errors are:Przypadkowe sformatowanie dysku, usunięcie kluczowych plików lub zapisanie nowych danych na dysku przed stworzeniem kopii zapasowej mogą prowadzić do utraty ważnych informacji. Najczęściej występujące błędy ludzkie to:

• Accidentally formatting the disk: It is common for users to accidentally format the disk thinking that it is a different disk or partition. In such a case, if new data has not yet been written to the disk, there is a good chance of recovering the lost files with the help of the right data recovery software.

• File deletion: Accidentally deleting files is another common cause of data loss. Even after emptying the Recycle Bin, files can still be recovered, as long as they have not been overwritten by new data.

• Write new data to the disk: Writing new data to a disk that previously contained lost files can make data recovery difficult or even impossible, because the new data can overwrite the lost data.

Malware and Viruses

Malware or virus attacks can corrupt the data on your drive, making it unreadable to your computer. Viruses can also cause file system failures, making it difficult to access information. Common malware scenarios include:

• Ransomware: This is a type of malware that encrypts data on your disk, demanding a ransom to decrypt the files. In the event of a ransomware attack, it is not always possible to recover your data without paying the ransom, unless there is a backup or a decryption tool.

• File-destroying viruses: Some viruses intentionally damage or delete files, which can lead to their loss. Antivirus software can help detect and remove such viruses, but recovering corrupted files may require specialized data recovery tools.

Mechanical failure

A hard drive drop, overheating, read/write head failure, or other physical damage can cause serious damage to the hard drive. In such cases, immediate shutdown of the device is essential to minimize further damage. Common mechanical failures include:

• Read/write head damage: The read/write heads can become damaged due to a disk drop or other mechanical shocks. In this case, data recovery may require the intervention of a specialist who can replace the damaged heads and recover the data from the disk platters.

• Overheating: Hard drives are susceptible to overheating, which can lead to mechanical failure. Regularly cleaning your computer and ensuring proper ventilation can help prevent hard drives from overheating.

To increase the chances of successful data recovery, it is important to accurately diagnose the cause of the problem. In some cases, this may require consulting a specialist, especially when the damage is the result of a mechanical failure.

• EaseUS Data Recovery Wizard – a program that allows you to recover data from various loss scenarios, such as disk formatting, system failure or malware attacks.

In the event that we are dealing with a situation where damage to data blocks covers the initial area to a large extent, we can use a special scanning method available in StrongRecovery. This is called "reverse scanning". To enable this mode, simply run the program, select the disk in the disk selection window using the settings (right mouse button -> settings), and the following window will appear:

Just select the option: "Damaged - REVERSE MODE (scan data from back to front)" and click "OK".

Steps to Take to Minimize Losses

When recovering data from a damaged hard drive, it is important to take the appropriate steps to help minimize losses and increase the chances of recovering your files:

1. Don't panic: Although a hard drive failure can be stressful, it's important to stay calm and not make hasty decisions. Read error messages and seek professional help if needed.

2. Turn off the device: In the event of a mechanical failure, immediately turning off the device can prevent further damage and increase the chances of successful data recovery.

3. Don't try to repair the drive yourself: Attempting to repair the hard drive yourself can lead to further damage and make the data recovery process more difficult. Trust the professionals who have the right tools and knowledge.

4. Back up your recovered data: After your data is recovered, make sure you create regular backups to prevent future problems. Store the copies in different locations for added protection.

Preventing Data Loss in the Future

To prevent the stress and frustration of data loss, it’s worth implementing the right prevention strategies:

Back up regularly

Backups are key to protecting your data. Make sure you’re making regular copies of your important files, either using external hard drives, the cloud, or both. Regular backups are the most important step in keeping your data safe. Set up automatic backup schedules so you don’t forget this important task. Store copies in separate locations—for example, one in the cloud and one on a physical drive—to minimize the risk of losing data due to a drive failure.

Malware Protection

Invest in solid antivirus software to protect your devices from malware and virus attacks. Update your software regularly to ensure maximum protection. Good antivirus software can detect and block threats before they can harm your data. Make sure your software is set to automatically scan your system and update it so it is always ready for the latest threats.

Physical Security of Storage Devices

Take care of the physical security of your storage devices, such as hard drives or pen drives. Store them in safe places, protecting them from falling, overheating, or other mechanical damage. Hard drives and other storage devices are susceptible to physical damage. Store them in places that are free from dust, moisture, and extreme temperatures. Regularly check that the media is in good condition and shows no signs of wear.

Education and awareness

Educating users on best practices for storing and protecting data is key. Regular training and reminders can help prevent human error, which is one of the leading causes of data loss. Users should be aware of the risks associated with opening suspicious email attachments, downloading software from unknown sources, and using unsecure Wi-Fi networks.

Monitoring and auditing

Regular monitoring and auditing of IT systems can help detect potential threats and issues before they cause significant losses. Use hard drive health monitoring tools that can indicate impending failures, such as SMART (Self-Monitoring, Analysis, and Reporting Technology). Regular security reviews of your network and systems can help identify weak points and take preventive action.

Backup and Restore

Make sure you have a well-defined backup strategy and restore procedures. Test your restore procedures regularly to make sure they are effective and can be used when needed. Testing your restore procedures is often overlooked, but it is essential. Make sure you can restore data from backups quickly and efficiently. Document the restore process so everyone on your team knows what to do in an emergency.
