Yes exactly, this part of the drive I use for experiments.

Purity of the experiment is not achieved, because I have the old method
to partition a disk.
But now I see how it was supposed to be:)

In the previous experiment, there was already ada0s4!!!!
I did not think, that the system shows me that a breakdown of the disk
that once was there.
I thought, that gpart made a record in the MBR and suitable recording on
slice.
And when I tried to enter the following command system would 'already
exists' !
Modify the partition of the system did not give me too.
On the one hand it is very good that nothing is lost, and with another
inexperienced person is misleading.
Maybe print a warning if the type of an existing entry in the slice is
not the type to MBR?
In any case, thanks for the tip-off:)
