Append following line: blacklist floppy Save and close the file. Now reboot the Linux server: # reboot Share this tutorial on:TwitterFacebookGoogle+Download PDF version Found an error/typo on this page?About the author: Vivek Gite is a seasoned sysadmin and a trainer for the Linux/Unix & shell scripting.
