According to http://www.seasip.info/VintagePC/floppies.html the teac
fc-1 was designed for unix workstations, and not really as a PC floppy
drive, and thinks making it work is pretty unlikely.  Some other pages
indicated programing docs for the drive says it requries a special scsi
command sent to switch into 1.44M mode.

A few hints found:
Disable HD emulation of removable drives (many adaptecs have this bios
option).
Disable disconnect on the drive (scsi bios option)
Force to 10MB/s or 5MB/s max (scsi bios option)

The commands: scsiformat, scsiinfo, scsi-config, and such may also be
helpful.
