From another post:
In KDE, in Knoppix 3.2, for an internal LS-120 drive, right click on the desktop, select create new, floppy device. Name it LS-120, and set the device to /dev/sda, then click ok. This should give you a desktop icon for the LS-120. Put a floppy in the drive, click the icon, and it should display the files in Konqueror after a few moments. Knoppix recognizes these drives as scsi devices.
