The issue is that upon reading back a disk that has

bad sectors start appearing more and more frequently (though most of the data is still
OK). I tried disabling TG43 just to see if it made a difference, and it does - with TG43
disabled sectors written past cylinder 43 read back as garbage.
The SuperCard is apparently not using a suitable amount of write
precompensation for the drives you're using.
