Those filesystems (ZFS, BTRFS) have robust error correction, but every modern filesystem has checksums for every block. Checkdisk isn't powered by magic. Also

Those filesystems (ZFS, BTRFS) have robust error correction, but every modern filesystem has checksums for every block. Checkdisk isn't powered by magic. Also, look into TCG Pyrite. Almost all consumer drives with SED features are Pyrite.

Now it’s up to you if you choose to educate yourself on this topic or remain a fool. > Checkdisk isn't powered by magic. What is “checkdisk”? If you’re talking about chkdsk, or Check Disk, or fsck like tools - none of those require checksums to do what they do. At a basic level they check the integrity of on disk data structures - the actual connectivity, valid counts, etc. How in your mind does a checksum contribute to this task? Chkdsk exists for FAT32, which you already seem to admit has no checksums. How do you think it works? > Also, look into TCG Pyrite. Almost all consumer drives with SED features are Pyrite. What does this have to do with anything - it certainly isn’t filesystem level encryption.
