1 Disk imaging tools

One of the most common and reliable ways to recover data from a system crash is to use a disk imaging tool. A disk imaging tool creates a copy of your entire disk or a specific partition, including the file system, the boot sector, and the metadata. You can then restore the image to a new disk or a different location, or mount it as a virtual drive and access your files. Some of the popular disk imaging tools are Clonezilla, Acronis True Image, and Macrium Reflect. These tools can also help you create backups, clone disks, and migrate data.

In my experience, the appropriate data recovery tool depends on the nature of the system crash. For accidental deletions or file corruptions, user-friendly tools like EaseUS or Recuva are effective. In more complex scenarios involving OS issues or hard drive failure, advanced tools like TestDisk or Disk Drill, with features for partition recovery, prove invaluable. Cloud-based backup solutions, such as Backblaze or CrashPlan, are proactive measures for data recovery. The best tool choice depends on the specific circumstances surrounding the crash and the type of data loss incurred.

There are many tools to recover data from system crash. But in my experience is always best to synchronize users system with cloud accounts like One Drive or Google Drive etc. Even if the system crashes, you just need to install operating system and login with user's cloud credentials. and you get your data back as it is.

2 File recovery tools

Another option to recover data from a system crash is to use a file recovery tool. A file recovery tool scans your disk for deleted or lost files and tries to recover them. This can be useful if your disk is still functional but some files are corrupted or missing. However, file recovery tools may not work if your disk is severely damaged or overwritten, or if your files are encrypted or compressed. Some of the well-known file recovery tools are Recuva, TestDisk, and EaseUS Data Recovery Wizard. These tools can also help you recover data from other devices, such as USB drives, memory cards, and cameras.

3 Live CD tools

A third option to recover data from a system crash is to use a live CD tool. A live CD tool is a bootable disk or USB drive that contains an operating system and a set of utilities that can run without installing anything on your hard drive. You can use a live CD tool to access your disk and files, repair your system, or copy your data to another device. Some of the popular live CD tools are Knoppix, Ubuntu Live CD, and Hiren's BootCD. These tools can also help you diagnose hardware problems, test your system performance, and erase your data securely.

4 How to choose the best tool

When selecting the best tool for data recovery from a system crash, there are a few factors to consider, such as the type and extent of the damage, the size and format of your disk, the availability of backup and recovery media, and the urgency and importance of your data. To ensure the best results, you may need to try different tools or combine them. As a guide, if your disk is physically damaged or inaccessible, create a copy of it using a disk imaging tool. If your disk is functional but some files are deleted or lost, use a file recovery tool to scan it. If your system is corrupted or unbootable, boot it using a live CD tool to access your disk and files. If you have a backup or recovery media, restore your system and data with them. Finally, if you have sensitive or critical data, use a professional data recovery service to recover it safely and securely.

5 How to prevent data loss

To prevent data loss from a system crash, it is important to take the necessary steps to protect your data and system. Creating regular backups and storing them in a separate location is essential. Additionally, you should use antivirus and firewall software to protect your system from malware and cyberattacks. Regularly updating your system and software is also important to fix bugs and vulnerabilities. Furthermore, you should monitor your disk health and performance, replace it if it shows signs of failure, and avoid downloading or opening suspicious files or links that may contain viruses or ransomware. Lastly, using a surge protector or a UPS can protect your system from power fluctuations or outages.
