Suppose that during an asynchronous parallel SCSI data transfer, someone removes a USB drive that is the intended target of the transfer. How would the initiator know that the error has occurred during these phases:

° Bus-free

° Selection

° Command

° Data

° Status

° Message

° Reselection

a) During which of the phases is it possible that good data may be written to the drive 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?
