These 12 are together.  (Three real sectors.)

dd if=/dev/zero bs=1024 count=12 seek=1073006628 of=/dev/sdc1

Oh I get it. Yeah that works. In this case seek= isn't LBA but is a multiple of 2, same as the block size. NEVERMIND! Ignore the man behind the curtain….

Nevertheless if there's a backup, I'd nuke these drives with ATA Secure Erase. And definitely schedule regular smart tests to keep an eye on them. It's a lot of bad sectors on one disk.
