Article Title: Hard Disk Data Recovery and Partition Table recovery in Linux. Linux is a technology channel of the IT lab in China. Including desktop applications, Linux system management, kernel research, embedded systems, open source, and other basic categories of Hard Disk Partition tables or data loss, is a headache. Fortunately, a considerable number of tools are available to restore data.
Experience testdisk, restore a partition table on the hard disk, and retrieve important data. The entire process took less than 10 minutes and does not require system restart (requires a specific hardware environment ).
Does partition damage the partition table on the hard disk ?). Colleagues use easy recovery: in Advanced recovery mode, partition tables cannot be scanned, so data cannot be restored. In RAW recovery mode, data is found and recovered, but cannot be used.
Get the hard disk, connect it to the mobile hard disk box (it is recommended that computer maintenance personnel keep it, hard disk maintenance is commonly used), and connect it to my ubuntu system.
1. Check hard disk status
Connect to the mobile hard disk, turn on the power of the mobile hard disk, the hard disk turns stably, no abnormal sound. Therefore, it is determined that the hardware works normally. No mobile disk is found in nautilus. The command line checks whether the device is recognized by the system:
User @ ubuntu :~ $ Ls/dev/sd *
/Dev/sda/dev/sda1
The results show that the hard disk and primary partition are found, but the extended partition is not recognized.
2. Install testdisk
User @ ubuntu :~ $ Sudo apt-get install testdisk
3. Run testdisk and fix it.
User @ ubuntu :~ $ Sudo testdisk
4. Reconnect the hard disk and check
The reason why the system is not restarted is mainly because the mobile hard disk box is used. If you use IDE directly, restart the computer. After you reconnect the mobile hard disk, you can view the three extended partitions in nautilus and perform data operations.
