How to repair a partition table in Linux?
The partition table can be repaired using the following method:
- To use the fdisk command: log into the Linux system, open a terminal window, and type the command sudo fdisk -l to list all the hard drives and partition information in the current system. Locate the hard drive where the partition to be repaired is located and then enter the command sudo fdisk /dev/sdx (x represents the disk identifier) to enter partition editing mode. Type ‘m’ to view the available command list. Type ‘p’ to print the partition table, check for any errors. If there are errors, you can use the ‘d’ command to delete the erroneous partition, then use the ‘n’ command to create a new partition, and finally use the ‘w’ command to save the changes.
- Utilizing TestDisk Tool: TestDisk is a free open-source tool used for repairing lost or damaged partition tables. Firstly, install the TestDisk tool. Then, open a terminal window, type in the command sudo testdisk and press Enter. Choose the hard drive to be repaired, then select the partition type (such as Intel or EFI GPT). In the partition table, choose the partition table type (such as MBR or GPT). Next, select the “Analyse” option to analyze the partition table. If errors are found, use the “Write” option to save the changes.
- To utilize GParted tool: GParted is a graphical partition editing tool that can be used to repair partition tables. After installing GParted, open the application. Select the hard drive to be repaired, then choose the “Create Partition Table” option from the “Device” menu. Select the type of partition table to use (e.g. MBR or GPT). Finally, use the “Apply” option to save changes and repair the partition table.
Before repairing the partition table, be sure to backup all important data to prevent any unexpected data loss. Repairing the partition table may result in data loss or inaccessible data.
