Hi there,

Error mounting mount exited with exit code 1


In Linux, you might encounter an issue where your drive can’t be mounted maybe during startup. This is mostly caused by file system failures. There are several reasons why this happens. Some may be caused by faulty utilities or device driver which sometimes happens when you are using third-party utilities. Another possible reason is a sudden power outage which can really damage the data in your hard drive.

And when a file system failure happens, you can experience stuffs like the system suddenly freezes, the file system doesn’t mount, and sometimes even if you managed to mount the file system you may notice some odd behavior. When a file system failure happens, it can be fixed most of the time when you use the command “fsck” or the front end to ext2/ext3 utility.

If your drive didn’t mount, run the following command in the terminal:

  • e2fsck

But if the drive was successfully mounted, you need to unmount it first by running the following command:

  • e2fsck -f /dev/sda3

Where “-f” will do force checking in the file system even if it’s clean. “/dev/sda3” represents the partition. You can also run any of the following commands to check for alternative-superblock locations:

  • mke2fs -n /dev/sda3​
  • dumpe2fs /dev/sda3|grep -i superblock

You can repair a file system using alternative-superblock by running the following command:

  • e2fsck -f -b 8193 /dev/sda3

But as recommended, you should create a backup first before doing any repairs on your file system. Run the following command to create a backup:

  • dd if=/dev/sda2 of=/disk2/backup-sda2.img

But make sure you have enough space before creating the backup.
