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
3928+1 records in
3928+1 records out
16478679040 bytes (16 GB, 15 GiB) copied, 156.816 s, 105 MB/s

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)
    2596 non-contiguous files (0.4%)
    1226 non-contiguous directories (0.2%)
         # of inodes with ind/dind/tind blocks: 0/0/0
         Extent depth histogram: 638434/974/3
 9995951 blocks used (13.05%, out of 76571648)
       1 bad block
       3 large files

  515535 regular files
  117354 directories
      57 character device files
      26 block device files
       0 fifos
     284 links
   67853 symbolic links (61332 fast symbolic links)
      61 sockets

  701170 files

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