Indeed. That's why I specified /silent/ corruption. If the stack returns an explicit error, that is correctable (assuming the other disks don't error and return the correct data). Sadly, a large number of SSDs (and nearly all cheap USB thumb drives / SD cards / eMMC devices) will happily return silently corrupted data.
