Please note, that Linux offers also 3rd method - integritysetup(8) - it 
works on block level - device mapper - (basically adding metadata with 
checksums for each block - to make it space efficient, these metadata 
blocks are "clustered" (grouped metadata for several blocks until they 
fill whole block). Integritysetup allows checksums for complete 
filesystems that do not have them (like ext4 that added metadata 
checksums but not data checksums).

Curious if, for example, RAIDframe could do something similar? There is 
ECC mentioned in manual on 
https://www.pdl.cmu.edu/RAIDframe/raidframebook.pdf but it seems to be 
not related to RAIDframe features.
