Fun question: what if a relocation table gets corrupted? And what protection is there against that possibility? You can bet it's not the same ECC as on data blocks. The rest is left as an exercise for the reader. ;)

uh oh, I recognize this one. Love to have a file corrupt after months at rest with no access logged and no mtime changes because a file on a neighboring track needed rewriting (SMR, of course).
