Hello i just installed ubuntu i didn't choose first option that will erase all your data
i choose /dev/sda2 which is my hdd drive 1TB and mounted to /home and my sdd which is 256gb mounted to / and now i can't find my files and folders on my hdd drive the hdd drives shows that there is 931gb size but my hdd drive is 1TB and i think this 80gb of missing size is my files and folders but don't know how to recover it
fdisk -l
