This is the whole story. The first time I wrote to the tape after running btape (including the autochanger test) was part of a full backup to 7 tapes. All the tapes filled to 400 Gigs roughly except this one, which errored at 52 Gigs at which point bacula moved to the next appendable volume.
Next, I removed the volume from the pool, rewound it, wrote an EOF, relabeled, and added to the pool again. Then I ran an incremental backup to fill the tape up to see if it would error again. So as you said, it filled it with 600 some gigs of compressed data, instead of erroring out at 52G like I expected. Basically compression got turned on without me knowing it or asking for it. The backup I ran last week of the *same exact* data did not fill any tapes over 400, meaning compression was off then. Regardless, the point of the exercise was to elicit an error on the tape. I'm going to try again with btape fill and then move on, assuming the tape is good. Thanks for replying.

I should try to word my questions better :) Yes, I understand that flipping a bit does not allow data on tape to magically reorganize itself on the tape. It must be rewritten of course.
