I/O error, dev fd0, sector 0 Jul 05 12:04:42 dell01 kernel: end_request: I/O error, 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 blk_update_request i/o error dev fd0 vmware 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.

I suppose the drive could be bad, I will test it with a different floppy drive.
