We got rid of all of our 800 bpi tapes a long time ago- sometime around 1990 I think, because the new version of MVS we were installing at the time no longer supported 800 bpi. Since we had a major customer who required that support, we built a front-end read the tapes create a disk file job on VM. We ran that way for a year or so until our customer was able to upgrade to - 1600 bpi. I don't know if VM still supports 800 bpi or not.
In any case, even if you have OS support, not all 3420 type tape drives can read all densities. We still have a few (at least we will have them a couple more months) 3420 type drives. Some are dual 1600/6250 bpi and some are 6250 only. What brand and model are your tape drives? How are they gened?
