In Linux the floppy is generally /dev/fd0 (equivalent to a: in Windows ).
The standard mount point for floppies is /media/floppy. You can easily mount the floppy with the command:
mount /media/floppy
If you have a line like this in /etc/fstab:
/dev/fd0 /media/floppy auto user,noauto 0 0
Note on Laser Servo Diskette Drives
If your floppy drive is actually a Laser Servo Diskette (LS120) drive, this will be named /dev/hdc or /dev/hdd
