I did actually arrange that all the SCSI errors it faked caused the
right retry behaviour at the SCSI level when I did that. Perhaps I
should have commented that fact.

Well the retry needs to e.g. include a bus reset prior to retrying.

Thats possibly true for some situations. You might also want to avoid
issuing resets as much as you can because they are a rather good source
of "my drive
went away" error reports with the IDE layer (and they take forever).

libata does a reset at the beginning of the probe...
