But SCSI devices have their own controller, which performs all of the
error checking, etc. on the prepping and then just ignores bad areas of
the HD (i.e. they are not counted). On the Amiga floppy system,
wouldn't the Amiga device driver be responsible for performing this (or
similar) function SINCE THERE IS NO SCSI CONTROLLER FOR THE DRIVE???
