AFAIK, even for the simplest case where corruption happens between a
head and a disk platter during write operation - the RAID has no way
to detect that. Unless it discovers later that the checksum on
another disk is wrong, and it is automatically updated to reflect the
corrupted data. Does it produce a message during resync in such case?
Someone here should be able to answer this.
