I seem to have lost some data capacity on a drive

Hi,
One of the drives on my system has lost after fiddling with partition table.
There where some small partitions.
Now it seems to have lost some space.

Code:

 df
Filesystem      Size  Used Avail Use% Mounted on
devtmpfs         12G     0   12G   0% /dev
tmpfs            12G   28M   12G   1% /dev/shm
tmpfs            12G  1.5M   12G   1% /run
/dev/sda1        50G  8.0G   39G  17% /
tmpfs            12G     0   12G   0% /sys/fs/cgroup
tmpfs            12G  4.0K   12G   1% /tmp
/dev/sda6        57G  1.2G   56G   3% /home
tmpfs           2.4G   40K  2.4G   1% /run/user/1000

You probably have unallocated space on the drive. The easiest way to check is with gparted. That will show all the partitions and any unallocated space, which can be used by expanding an existing partition or creating a new partition. Is the drive in question sda, or sdc? What happened to sdb? It appears that there is an extended partition on sda (sda6) but no logical partitions in it. This appears to be an imperfect partitioning attempt.
