At this screen:

                          FreeBSD Disklabel Editor

Disk: ad4       Partition name: ad4s4   Free: 0 blocks (0MB)
Disk: ad4       Partition name: ad4s3   Free: 0 blocks (0MB)

The following commands are valid here (upper or lower case):
C = Create        D = Delete   M = Mount pt.            W = Write
N = Newfs Opts    Q = Finish   S = Toggle SoftUpdates   Z = Custom Newfs
T = Toggle Newfs  U = Undo     A = Auto Defaults        R = Delete+Merge

Use F1 or ? to get more help, arrow keys to select.

--------------------------------------------------------------

Unfortunately at this point when I choose W to write the changes I get 
the following error:

Unable to add /dev/ad4s3b as a swap device: the device is busy

This is the existing swap partition so I do not quite understand why I 
get this error

Then I choose OK and then I get:
Error mounting /dev/ad4s4d on /data : No such file or directory
