Suppose during an asynchronous parallel SCSI data transfer someone removes a floppy disk from the drive that is the intended target of the transfer. How would the initiator know that the error has occurred during these phases:
• Bus-free • Status
• Selection • Message
• Command • Reselection
• Data
a) During which of the phases is it possible that good data may be written to the floppy if the data transfer is a "write" operation
b) If the transfer is a "read," at which point would the system have good data in the buffer Would the system ever acknowledge this data
