I do not have documentation for these drives. If I format them on an older machine as 720K normal density, then the drive has no problem reading and writing to the disk. However, I have been unable to get the drive to recognize HD floppy disks. I was able to install this drive into my PC and I can access it with and Adaptec SCSI card.

We have access to new old stock of of TEAC FD-235HS -711 SCSI Floppy disk drives, these consist of a FD-235HF-3700 floppy drive mechanism with a TEAC FC-1 SCSI floppy disk controller bolted on. Because of this I have been trying to find a more robust solution to work with my modern PC running Windows 10. These work most of the time, but the floppy drive mechanisms are inferior to legacy drives and they are slow and error prone. (Some of our equipment still had 5.25' inch floppies.) As modern PC's don't have floppy disk controllers, we have purchased external USB floppies. Consequently, this means that it is often necessary for me to transfer data to modern computers via 3.5' floppy disk. This is an Avionics shop environment, so we can't just upgrade to modern hardware as we have to use whatever was specified at the time of design.
