Electrical - Is this legal to code?

I dug a trench from the garage to a toolshed, and put about 30 feet of
12-2 UF cable underground to the shed. *Before filling the trench, I
decided that maybe it would be best to put two of these cables in so I
have two circuits in there, mainly because it gets so hot in there that
I might put in a small air conditioner.

The first cable I installed was some UF cable that I got at an auction.
It's unused cable, but apparently old stock. *The reason is that it does
not have a ground wire. *The second cable is brand new, because I did
not have enough of that old stuff to go twice. *I did not realize there
was no ground in that cable until I filled the trench, or I would have
just bought all new cable.

Anyhow, I ran one cable to the left+rear of the shed, the other to the
right+front. *After I get it all stapled and into boxes is when I
realized there is no ground on that one cable. *Oddly enough they both
look the same. *They are gray and 12-2 UF. *I did not know they even
made gray without ground. *I recall some old white UF that came without
a ground years ago.

Anyhow, this is what I plan to do. *Both cables are on a separate
breaker at the source (garage). *In the shed, I will ground the ground
wire to the box from the cable that has a ground. *On the second cable
without the ground, I'll run a bare or green wire to the other circuit
that has the ground wire. *This will just be a bare copper wire (or
green insulated) across the rafters to a box on the other circuit.

Electrically speaking, this is a completed ground, but I'm wondering if
an inspector would allow such a connection?

My other option, seems to be to run both cables into one box, near where
they enter the shed. *That way, there is one ground wire to that box no
matter what. *Then run my outlets and lights all to that box, but use
the hot and neutral wires as planned to have two circuits. *This might
make more sense but will need more materials to do.

By the way, this will not be inspected. *This is rural property and they
dont bother with small things like this. *I'm only asking both for
resale value (at which time there could be an inspection), and just to
know how this would be viewed.

I know I'll be corrected if I'm wrong, but I'm going to throw this out
anyway. In fact I'll word everything as a question, so I won't
actually be wrong, just curious. ;-)

I believe that code requires a disconnect for out builidings that can
be reached from the door. Since you are planning to have 2 separate
circuits, do you need 2 disconnect switches? Are 2 disconnects allowed
or should you have used 1 run to a disconnect panel and then splilt
the circuits inside the shed? (A bit late for that, I would think)

Since one circuit comes into the shed at the left-rear, wouldn't you
need to run a wire towards the front for the disconnect?

If so, how will that impact the running of your ground for the
ungrounded circuit?
