The standard for full-disk encryption (FDE) is XTS mode or ESSIV-AES-CBC. XTS tweaks each block within each sector differently (and hence avoids ECB's problems) and is considered the best choice available at the moment. ESSIV-AES-CBC works by using AES-CBC with the IV being the hash of the sector index. The problem with this mode is that you can flip bits ...

Better is a subjective term. However for the choice between ECB and CBC, the choice should be CBC for almost all situations. Although ECB and CBC are modes of operation of a block cipher, you could also turn this way of thinking around and see the block cipher as a configuration option for the mode of operation. The mode of operation has a big influence on ...

My own two cents on this is that it started with a psychological bias, due to the illusion that AES-ciphering consecutive numbers in CTR mode is a weakness compared to the recursive AES-ciphering in CBC. Actually, I think I remember it was more of less told during that course on Coursera, that a consensus about the inoffensiveness of that counter with regard ...
