How to fix print_req_error: I/O error, dev fd0, sector 0 error

After a fresh install of Ubuntu, my terminal was being flooded with “print_req_error: I/O error, dev fd0, sector 0” error.

dev fd0

This is because, your kernel thinks you have a floppy disk fd0, but cant find one. To fix this issue, you can run the following in your terminal:

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

Misc: If you are deploying a new virtual machine, you can avoid this issue by deleting the Floppy Disk drive.

View progress when using dd command

While using “dd”, by default it does not show the progress nor status of the transfer. However, you could use the flag “status=progress” to show the status/progress of the transfer. Here is a screenshot:

This flag is available in the newer version of dd. Here are the CLI outputs for the text ninjas:

$ sudo dd if=archlinux-2019.06.01-x86_64.iso bs=4M of=/dev/sdd status=progress oflag=sync
641728512 bytes (642 MB, 612 MiB) copied, 16 s, 39.1 MB/s
153+1 records in
153+1 records out
643825664 bytes (644 MB, 614 MiB) copied, 16.4601 s, 39.1 MB/s

PS: Use dd (data duplicator) with caution. ‘ddis also known as disk destroyer  in an alternate universe.
