Data recovery from a linux hard drive
Recovering data from a Linux hard drive can be a difficult task, but possible under certain conditions. Here are some steps that can help you recover lost data:
1. Stop using the drive: If you discover data loss on your Linux hard drive, stop using it as soon as possible. This will avoid overwriting deleted files and increase the chances of successful recovery.
2. Create a copy of the entire contents of the drive: Use the dd tool or another program to create an exact copy of the contents of your hard drive to a second drive (perhaps another physical HDD or SSD). This will provide a safe working copy for recovery operations.
3. Use specialized programs for data recovery: There are a number of free and commercial tools for working with different types of Linux file systems (such as ext4) and performing the process of scanning/recovering deleted files.
- TestDisk is one of the most common toolkits for data recovery on Linux. It can scan the disk and try to find remote partitions or file systems.
- PhotoRec is part of TestDisk and specializes in restoring photos, videos, audio files and other typical media formats.
4. Contact professional data recovery services: If you do not have enough experience or are confident that you can handle all this yourself, it is recommended to contact a professional data recovery company for help. This is especially relevant in case of serious damage to the hard disk.
Important note: Always back up your data! Regular creation of backups is the best way to prevent data loss due to possible problems with the hard disk or software errors
