dev fd0, sector 0What do they mean? 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 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 floppyOutput:floppy 95465 0Open file called /etc/modprobe.d/blacklist:# vi /etc/modprobe.d/blacklistListing 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 floppySave and close the file. Now reboot the Linux server:# rebootShare 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.

Whenever I try to boot, my computer says "Error getting authority: Error initializing authority: Could not connect: No such file or directory (g-io-error-quark, 1) Welcome to emergency mode!..." followed by abunch of things I o error dev can do. It spits the same error out if I ctrl-d to boot into default mode, and the fstab file matches the drive UUIDs perfectly. But I think I found the culprit. When I run blkid, it takes a while, and then spits out "blk_update_request: I/O error, dev fd0, sector 0" followed by the drives' data. What is happening, why, and how do I fix it? I tried the possible duplicate question, but it is a slightly different error and the solution doesn't work. filesystem share|improve this question edited Jan 9 at 15:31 asked Jan 9 at 14:17 Ben 62212 1 Possible duplicate of "Buffer I/O error on device fd0, logical block 0" error –Mark Kirby Jan 9 at 14:38 I figured out that I can get it to work if I boot into recoovery mode and then tell it to fix broken packages. It doesn't seem to matter if this was sucessful or not. Then I can continue booting and it works. –Ben Jan 11 at 12:20 Update: I discovered it doesn't NEED to be the fix broken packages option. It will in fact work with any option t
