Private data can still be recovered when you format your Linux/Microsoft Windows machine.
There are two possible solutions. The first solution is using the dd command:
dd if=/dev/urandom of=/dev/sda
This command will overwrite the data stored on the /dev/sda partition with random junk, however, there is a disadvantage with using the dd command and that is the speed that it takes to overwriting the data. The second solution is to use the shred command:
shred -v -n 1 /dev/sda
This will overwrite the data on the /dev/sda partition with random junk and at a much faster speed.
