I've made a library and am trying to save it to a floppy disk so I can put it in an ender chest, to ensure that I don't lose the file until I find a suitable place to upload it. But for some reason when I run cp to copy the file from the hard drive to the floppy, nothing happens. I type "cp -r -v /lib/... /mnt/309/lib/..." into the shell, it prints that the file was copied, but when I run "ls /mnt/309" it shows nothing. No directories, no files. Why isn't this working?
