UFS usb external disk acting weird

Hastur

Hastur

/dev/ada0
Code: 
I have 3 other usb drives with ufs mounted and working.
I am not sure what happened with this 4th disk, I wonder
if I somehow had an unsuccesful install which picked
this disk since it seems to have efi and swap partition.
I had used it a year ago to hold torrent files like
books movies.
It constantly says device busy.

root@drizzle-drizzle:~ # gpart show ada0
=>       40  488397088  ada0  GPT  (233G)
         40     532480     1  efi  (260M)
     532520  479715320     2  freebsd-ufs  (229G)
  480247840    8149288     3  freebsd-swap  (3.9G)
 
root@drizzle-drizzle:~ # gpart destroy  /dev/ada0
gpart: Device busy

I even started zfs and tried to make a zpool, with idea to
suck all the torrent files into 1 zpool with all 4 usb disks:

root@drizzle-drizzle:~ # zpool create titsborg /dev/ada0
cannot create 'titsborg': no such pool or dataset

This is is one ornrey bastard.

Any one know how I can press it back into duty?

Ok it seems I am being dumb.
ada0 is my ssd root disk.
