Upon doing;

crude but effective:
DISK=da0
offset=`diskinfo $DISK | awk '{ print $4 - 131072 }'`
dd if=/dev/zero of=/dev/$DISK bs=64k count=1
dd if=/dev/zero of=/dev/$DISK bs=64k seek=$offset
gpart create -s gpt ${DISK}
This is what I ended up doing.
I unplugged it, waited a few, re plugged and then I was able to delete/destroy.
I will keep your method on hand though as I prefer not doing a hot plug.
Hot plug? That just wipes the beginning and end of the disk. I would
erase 1M just to be sure.
The more elegant version is
gpart destroy -F da0
If it gives an error when doing that, disabling the safety may be
necessary: sysctl kern.geom.debugflags=16
Do that only when necessary. It usually is not.
