Hyper-V Linux I/O error, dev fd0, sector 0

Jul 17, 2018Hyper-V, Solutions to common problems you can fix yourself

In Microsoft’s hypervisor, Hyper-V, certain Linux based operating systems frequently display an error: IO Error dev fd0 sector 0.

This is caused by Hyper-V’s virtual floppy drive. There is no storage media attached to this drive, and for some reason the OS does not like that.

The Solution

To fix this, we can remove the floppy module. This must be done with administrative privileges.

Enter the following commands:

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