I think that df only checks mounted filesystems.

Mount the filesystem; get the size using df; unmount it.

Solution 2

You can use this command to see the size of partitions :

ls /proc/partitions

And I guess that its very difficult to find out how much space is free on a particular partition unless its corresponding filesystem driver were installed(mounted).

Hope it helps.
