written or printed on a paper label stuck to the top of the drive, not
stored digitally on the drive platter(s). I may be mistaken, but I have
a memory rattling around in my head of the bad block list even being
printed on greenbar paper at final test, which was then cut with
scissors and Scotch taped to the top of the drive. So, they were very
literally "written on the drive" in layman's terms.

Some of my drives have paper printouts of bad blocks that are folded and 
fit into a plastic sleeve that's attached to the drive.

Don't have access to brands/models right now, sorry. These would be the 
larger, full height, 80s vintage drives; possibly early SCSI and 
possibly accompanying Sun 3 gear.
