F-2 Supported Emulated Block Transfer Commands
The following table lists the supported emulated block transfer
commands and where you can find more information on them.
When an operation is unsuccessful, header word 1 of the drive response
contains a negative value (bit 15 = 1).
If an error occurs, the drive also returns a status word to indicate the
reason for the failure. The location of the status word is typically header
word 3 in the drive response, but will depend on the message.
