Have there been any SRB's not recovered apart from challenger?

I seem to remember something about pictures of a sinking SRB that didn't
have its chute deploy. If this is true did it float and eventually sink with
water entering? How quick where they there to take pictures and are these on
the net anywhere? Also why isn't the chute cut away just before water
landing? Seems like they get tangled and really form a mess for the divers.

the SRBs were recovered from STS-51L.. that's how they could determine
what went so terribly wrong.
I believe STS-4 boosters sunk, but I think all others have been
recovered just fine for later use.

I think  although they were recovered from Challenger, it was pretty obvious
from the  video that the  joint near the base leaked and melted the bottom
bracket allowing it to pivot and puncture the tank.

I still had sight then.

Obvious? Yes.. Recovered? YES
The guy was asking if SRBs has been lost, and I was pointing out that
STS-51L's boosters HAD been recovered - obviously not for re-use, but
that wasn't the question.

True, but not recovered in the normal way.  They found the pieces on the
bottom of the ocean.  Don't forget the range safety package was activated,
which opened the casings up with a linear shape charge.
