Researchers at the University of Southampton in the UK successfully stored the entirety of the human genome sequence onto an indestructible 5D optical memory crystal no bigger than a penny. The indestructibility claims are no joke since the discs can withstand temperatures up to 1,000°C, cosmic radiation, and even direct impact forces of 10 tons per cm2.

That’s not what a checksum is
They probably mean EC code? That said, you can use checksums to “correct” errors if you have redundant copies of the data (by reading from the other copy if one copy has a bad checksum)
Don’t make me show you the wikipedia article.
Can’t argue with that logic.
I guess I will go back to using dd to hack the Pentagon
