I have an issue with gpart, it will not let me delete partition ada0p2 =
responding with =E2=80=9CDevice Busy=E2=80=9D
The man page gpart(8) says this may be shown if a partition exists but I =
cannot seem to delete partition 2 in my case via gpart delete or gpart =
destroy=20
This is a used disk but new to the machine, I can modify the partition =
type and create partitions before and after partition 2 but I cannot =
delete it.
Here=E2=80=99s what I have tried so far:

I=E2=80=99m not sure where to go from here, I=E2=80=99m tempted to pull =
the drive and reformat elsewhere
I have all tried dd=E2=80=99ing the disk as root but dd /dev/ada0 errors =
with unauthorised.
Am I missing something obvious?
