I have dd error reading
# sudo dd if=/dev/sda1 of=backup.img bs=4M status=progress
16478679040 bytes (16 GB, 15 GiB) copied, 154 s, 107 MB/s
dd: error reading '/dev/sda1': Input/output error

I thought this probably means disk has bad blocks. I ran
# e2fsck -cfpv -C 0 /dev/sda1
/dev/sda1: Updating bad block inode.
700895 inodes used (3.66%, out of 19144704)

It apparently fixed not what important for
dd. How to fix what is needed?
