when you don’t have a floppy drive attached to Linux server. Solution is quite simple just disable driver for floppy and reboot the system. You can verify this with the following command (this solution works with RHEL, CentOS, Redhat, Ubuntu/Debian and other Linux distros) : # lsmod | grep -i floppy Output:floppy 95465 0Open file called /etc/modprobe.d/blacklist: # vi /etc/modprobe.d/blacklist Listing a module (driver name) in this file prevents the hotplug scripts from loading it. Usually that'd be so that some other driver will bind it instead, no matter which driver happens to get probed first. Sometimes user mode tools can also control driver binding. 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.

By switching to a terminal window during this 10 seconds I saw the error message [ 54.904480] end_request: I/O error, dev fd0, sector 0 being outputted. I assume this has to do with the floppy drive... but I don't even have a floppy drive! How do I disable this device and make this error message go away (and hopefully fix the long wait)? Thanks. ubuntu login share|improve this question edited Jul 22 '14 at 23:03 Cfinley 1,3953817 asked May 16 '10 at 14:05 Jarvin 5,35133260 add a comment| 1 Answer 1 active oldest votes up vote 1 down vote accepted Login to your system as you would normally do. Press alt+f2 . Type: sudo gedit /etc/fstab . Here, you should see a line with /dev/fd0 . Put a # to the beginning of that line, save the file, do a reboot. For example it looks like this: /dev/fd0 /media/floppy0 auto rw,users,noauto 0 0 Make it look like this: #/dev/fd0 /media/floppy0 auto rw,users,noauto 0 0 Let's disable the floppy then. Alt+f2 , sudo gedit /etc/modprobe.d/blacklist.conf . Start a new line with: blacklist floppy Reboot. share|improve this answer edited May 16 '10 at 14:24 answered May 16 '10 at 14:12 Shiki 11.3k1763126 Hmm... Tried this, and restarted, still getting the same error message. The problem is the error is happening with the device, not the mounting. –Jarvin May 16 '10 at 14:20 Just B
