My advice to host people is always to assume the worse and prevent
the drive from doing anything tricky. Specifically, reject any
MODIFY DATA POINTERS or RESTORE POINTERS, and in general just about
the command (if the drive does not beat you to it with a CHECK CONDITION).
Parity errors should not occur often (if they do, you are in big trouble
anyway). It is simply not worth the debugging and reliability problems
you get in using a complicated error recovery protocol rather than
just killing the command at that point and starting over.
