But, what's a "data check"? A phrase search of the same publication
reveals no definition, cross-reference, or glossary entry. Intuitively,
I'd expect it to mean an inconsistency detected not by hardware, but
by software, such as length read inconsistent with RDW, or not a
multiple of LRECL; i.e. the block appears physically OK, but contains
invalid data.
on I/O devices, "data check" is a well-defined term meaning that the
device hardware detected a media problem when reading or writing the
data. It does not include logical errors.
