How to mount a hard drive with data on CentOS?

To mount a hard drive with data on CentOS, you can follow the steps below:

1. Make sure the hard drive is connected to the computer and recognized. You can use the commands lsblk or fdisk -l to view the device name of the hard drive, such as /dev/sdb.
2. Create a directory for mounting a hard drive, such as /mnt/data. Use the following command to create the directory:
3. Create a new directory named “data” inside the “mnt” directory using superuser privileges.
4. Use the lsblk command or fdisk -l command to check the partition situation of the hard drive. If the hard drive is not partitioned, you can skip this step.
5. Choose the partition to mount based on the hard disk partition layout. For example, if you want to mount the data on /dev/sdb1 partition, you can use the following command:
6. Elevate to root privileges in order to mount the device located at /dev/sdb1 to the directory /mnt/data.
7. If the hard drive is not partitioned, you can directly mount the entire hard drive to a specified directory, for example:
8. Require elevated permissions to mount /dev/sdb to /mnt/data.
9. To verify a successful mount, you can use the command df -h to check the mounting status. If the mount is successful, you should see the mount point for /dev/sdb1 or /dev/sdb as /mnt/data.
10. To ensure that the hard drive is automatically mounted after the system reboots, you can add the mounting information to the /etc/fstab file. You can open the /etc/fstab file using the following command.
11. Open the file /etc/fstab using the command sudo vi.
12. Then add the following content at the end of the file (assuming you want to mount the /dev/sdb1 partition):
13. Use the default settings to mount the ext4 filesystem on /dev/sdb1 to the /mnt/data directory.
14. Save and close the file.

You have successfully mounted a disk with data on CentOS. You can access the data on the disk by accessing the /mnt/data directory.
