@matigo It's likely s Seagate 4096 then. There were a few full height 80MB drives but that one was really popular for a while. Then it became very unpopular for the previously outlined reasons :)
The worst MFM hard drive was made for the original IBM-AT. A company called Lapine. Almost every single drive self destructed.
The third worst to memory was the Quantum Bigfoot drives. As a Compaq certified repair person, I made a small fortune replacing those under warranty.
