Sure; consider the very common Samsung SFD-321B, particularly page 5: https://datasheetspdf.com/pdf-file/900360/Samsung/SFD-321B/1 Another type of "tri-Density" drive is the fairly common Teac FD-235J, which can do 720K, 1.44M and 2.88M. I've got a couple installed in older systems. They're all configured as media-sense, so the controller doesn't have to do anything special, other than support the 1M transfer rate. One surprise that I had was with a Toshiba Infinia P1 desktop--it came configured to support the 1.23M 360RPM mode in addition to the 720K and 1.44M 300 RPM modes. --Chuck
