Unable to GPT format the disk "ada6": gpart: geom 'ada6': File exists

I added 2 more Drives tonight but when I go to Volume manager to expand I get the error message below:

Tried wiping one of the disks now and got

Code:

[MiddlewareError: Failed to wipe ada6: dd: /dev/ada6: Operation not permitted]

??

Were these previously used in another array?

Please show me the output of these commands

gpart show ada6

gpart show ada7

Posted in individual blocks of [ CODE ] tags please

Nope, both are brand new WD red's
ADA6

Code:

root@Katrinelund:~ # gpart show ada6
=>		  0  15628053168  ada6  (none)  (7.3T)
			0  15628053168		- free -  (7.3T)

ADA7

Code:

root@Katrinelund:~ # gpart show ada7
gpart: No such geom: ada7.

Hmm, what the heck happened there... when I view disks I clearly see that I have a ada7 disk connected?

Guessing it's my sata card that's the root... it's SIL3132 based so should work but ordered a new one. This time a IOcrest card that's supposedly going to work!
