I'll bet you'll find that the drive isn't seeking back to track zero
correctly. All other tracks will be OK but there will be a small
buildup of shite on the slider knocking the head a tiny bit "inside" the
proper place for track zero.

What this means is that it partially overwrites track zero, and rewrites
a new one. But there will be a certain amount of interference between
the two tracks, and it will not successfully read.
