Buffer I/O error on device fd0, logical block 0 error and simply soultion

After installing openfiler, then I keep getting this error. Inside /var/log/messages and sometimes in console.
I though it is because my hard disk corrupt. Then I google  and found out the solution.

Buffer I/O error on device fd0, logical block 0

What 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 floppy
Output:

floppy                 95465  0

In my case, there is no /etc/modprobe.d, so i create the folder
# mkdir -p /etc/modprobe.d

Then, I create this file /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

# more/etc/modprobe.d/blacklist
blacklist floppy

Save and close the file. Now reboot the Linux server:
# reboot
