Indeed. The error/abort distinction is more about locking/recovery
than drive level semantics. We will still issue an ATAPI reset and
if need be fall back to an ATA reset. What we handle differently is
the assumption that the drive status registers are valid (they are
not), that we are in an interrupt handle an IDE phase (we are not)
and that we want to recovery/reissue or issue the next command
from this context.
