Wouldn't it be better to treat all adapters the same way? Of course
the adapter-driver should be responsible for 'getting the message out',
but everything beyond that is scsi-adapter independent. 

It would be logical for the recovery-strategy to be placed outside the 
adapter-driver.  This makes the drivers simpler and prevents a
duplication of the effort for good error-handling. Also inconsistencies
in error-handling would be less. Now I know this wouldn't help for IDE
drives, but I don't think anybody using IDE is really interested in
error-handling and -recovery. ;-)
