how do I write this

eb-5.0.11-16ab-1101.lzdsk

to a floppy? If I try dd if=eb-5.0.7-xx.lzdsk of=/dev/floppy the floppy drive looks like its writing but it doesn't make any noise and the comupter locks up. How do I write this??? Oh and the $ cat eb-5.0.11-yournic.lzdsk > /dev/fd0 dosen't work ether. its says $ suin't a command.
