How To Fix “blk_update_request: I/O error, dev fd0, sector 0” Error After Kernel Update on Ubuntu

In the world of Ubuntu, kernel updates are a common occurrence. However, sometimes these updates can lead to unforeseen errors. One such error is the “blk_update_request: I/O error, dev fd0, sector 0”. This error typically occurs due to issues with the floppy drive module, incorrect entries in the fstab file, or a problem with the kernel update itself. In this article, we will guide you through a step-by-step process to resolve this error.

Understanding the Error

Before diving into the solutions, it’s important to understand what the error message means. The “blk_update_request: I/O error, dev fd0, sector 0” is an error message that signifies an Input/Output error with the device ‘fd0’ at ‘sector 0’. The ‘fd0’ represents a floppy disk drive, which is a legacy hardware component that many modern systems do not use.

Solution 1: Remove the Floppy Drive Module

The first solution involves removing the floppy drive module from the system. This can be done by running a series of commands in the terminal.

sudo rmmod floppy
echo "blacklist floppy" | sudo tee /etc/modprobe.d/blacklist-floppy.conf
sudo dpkg-reconfigure initramfs-tools

Here’s what each command does:

• sudo rmmod floppy: This command removes the floppy module from the running kernel.
• echo "blacklist floppy" | sudo tee /etc/modprobe.d/blacklist-floppy.conf: This command creates a new configuration file that prevents the floppy module from being loaded at startup.
• sudo dpkg-reconfigure initramfs-tools: This command updates the initial RAM filesystem.

Solution 2: Check and Update the fstab File

The fstab file is a system configuration file that contains information about all the disk partitions and other data sources. If there are incorrect entries in this file, it can lead to the aforementioned error. To fix this, you need to check and update the fstab file.

Open the terminal and type the following command to open the fstab file in a text editor:

sudo nano /etc/fstab

In this file, ensure that the UUIDs of your drives match the entries. If there are any discrepancies, correct them, save the file, and exit the text editor.

Solution 3: Disable the Floppy Drive in the BIOS

Another solution is to disable the floppy drive in the BIOS settings. To do this, restart your computer and enter the BIOS settings. Look for an option related to the floppy drive and disable it. Remember to save the changes before exiting the BIOS.

Solution 4: Update the initramfs

The initramfs is a temporary root file system that is loaded into memory in the boot process. Updating it can sometimes resolve the error. To update the initramfs, open the terminal and run the following command:

sudo update-initramfs -u

This command updates the initramfs and applies any changes made to the system configuration.

Conclusion

The “blk_update_request: I/O error, dev fd0, sector 0” error can be a bit daunting, especially if you’re new to Ubuntu. However, with the solutions provided in this article, you should be able to resolve the issue. Remember to always backup your important data before making any changes to your system configuration. If none of the above solutions work, consider seeking further assistance from the Ubuntu community or a professional.
