Open your terminal pressing the Ctrl + Alt + T keys.
Check your available partitions from your terminal

df -h

Alternatively :

ls -lt /dev/sda*
# sda partitionlarının hepsini görüntüle

You will see an output similar to the following.

brw-rw---- 1 root disk 8, 2 Nis 20 12:48 /dev/sda2
brw-rw---- 1 root disk 8, 1 Nis 20 12:48 /dev/sda1
brw-rw---- 1 root disk 8, 5 Nis 20 12:48 /dev/sda5
brw-rw---- 1 root disk 8, 3 Nis 20 12:48 /dev/sda3
brw-rw---- 1 root disk 8, 0 Nis 20 12:48 /dev/sda

fsck -f -r /dev/sda5
