Fun. I dont know what geography this was for, but some drives I didnt recall seeing that were famous (to me at least) not mentioned:

- Seagate ST-238 - the 30mb RLL version of the ST-225

- Seagate ST-251 - the 40mb MFM

- Seagate ST-4096 - full height 80mb

I also didn't see Rhodime or Kyrocera.

I remember the first time I opened a Compaq machine with a Conner peripherals IDE drive. I was baffled. What the hell is this ? Definitely wasn't going to initialize that with Debug: G=C800:5. The classic way to low level most MFM drivers in the era. There was no google to put in a part number to get details on.
