For practical purposes, you can consider them as nonexistent.

Apparently IBM's AS/400 systems use disks with 520 bytes/sector.
This is closed technology.
MFM/RLL disks (remember?) didn't have a native sector size. I
remember formatting MFM disks with 256-byte sectors for use with
Acorn's ADFS and the built-in MFM controller on the Archimedes 4xx
series. That was some ten years ago, and it was already highly
bizarre at the time.
PCs have always used 512-byte/sector hard disks.
