Are you running Hatari with just floppy disks enabled (no ACSi disk, no GEMDOS 
disk) and no "patch timer D", no "boot faster ..." ?  Under these conditions, 
EmuTOS does not see drive B on my system.

If you have a GEMDOS disk, for sure you will see two drives due to Hatari 
patching the drivebits.
