Ubuntu – blk_update_request: I/O error, dev fd0, sector 0

filesystem

This happened after a kernel update. 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 a bunch of things I 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.

Your device doesn't have a floppy drive, but the floppy driver module is installed, so you have /dev/fd0, and many things will try to use it.

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

I have found the issue! Drilling down into the files using:

sudo du -a /home | sort -n -r | head -n 10

Shows the top 10 files taking up the most space, two of the biggest was .xsession-errors and my downloads folder. After going to the directory and using rm -f on the folders my /home is now only 6.1G!

Thanks to all that helped me to narrow down the issue and resolve it.

Ubuntu – “Error splicing file: Input/output error”

Got this error too when copying data from my new dashcam. Reason: I had accidentally connected the device to the USB 3.0 port. After I connected the device to the USB 2.0 port, copying went well.
