This lab introduced me to disk management and partitioning in Linux using command-line tools and virtual machines. I learned how to identify existing storage devices and partitions using commands like ls /dev/sd*, fdisk -l, and parted -l, then compare system changes after adding a new virtual disk. I also created and formatted a new partition with an ext4 filesystem, mounted it to a directory, and verified it using df. A challenge was understanding how partitions, filesystems, and mount points connect and how changes appear across different disk commands. Overall, it helped me understand how Linux manages storage at a low level and how new disks are prepared for use in a system.
