Everything you say can be prevented by a more robust filesystem ...
FALSE. I'm talking about hardware-level sector failures. A filesystem without checksumming can be made robust against reported bad blocks, but a bad block that the drive delivers as good can completely bollix ext3 or any fs without its own checksums. Drive manufacturers specify and (just) meet a rate of such bad blocks, low enough for non-critical applications, and low enough not to kill performance of critical applications that perform their own checking and recovery methods.
Denial is not a sound engineering practice.
