How do I fix this problem?A. This message appears when you don’t have a floppy drive attached to Linux server. Solution is quite simple just disable kernel: blk_update_request: i/o error, dev fd0, sector 0 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.

End_request I O Error Dev Fd0 Sector 0 Suse
CentOs 7 install in VMWare Workstation 9. I have removed the floppy drive from the VM configuration (as my host machine does not have one, and I http://www.cyberciti.biz/faq/linux-end_request-ioerror-dev-fd0-sector0/ haven't used one in literally 12 years).When the VM boots, an error message comes up:Code: Select allend_request i/o error dev fd0 sector 0After looking around online, it seems that the floppy module is loaded at start up by default, whether there is a floppy drive connected or not. This can be disabled by telling the http://www.centos.org/forums/viewtopic.php?t=47519 system not to load the module at start up, and apparently the different flavours of GNU Linux all have different ways of doing this. I've tried several methods, and all have failed as the module still loads on start up and the same error message still appears during boot. The methods I've tried are:Added Code: Select allalias floppy offto /etc/modprobe.conf and rebootedAdded Code: Select allblacklist floppyto /etc/modprobe.d/blacklist.confand rebootedAdded Code: Select allblacklist floppyto /etc/modprobe.d/floppy.confand rebootedIn each case those files did not exist as default and needed to be created, and thus far every method has failed. Does anyone have a definitive answer for how to disable the floppy module from loading on boot in CentOs 7 specifically?ThanksZep Top chemist Posts: 14 Joined: 2014/08/21 17:15:28 Re: Disable floppy module from loading on Centos 7 Quote Postby chemist » 2014/09/02 14:49:04 Actually, I have the same question.In my case C7 is native, and I do not have any floppy-drives.During booting systems halts rendering the same err

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)?

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 Shik
