The ERASE command causes part or all of the medium to be erased beginning at the current position. As used
here, "erased" means either the medium shall be erased or a pattern shall be written on the medium that indicates
the end of recorded data.
An Immed (immediate) bit of zero indicates the Device shall not return status until the operation has completed.
An Immed bit of one indicates that the target shall return status as soon as all buffered commands have
completed execution and the CDB has been validated. If CHECK CONDITION status is returned when the Immed
bit is set to one, the operation shall not be performed.
Long: The Long bit controls the distance to be erased. The drive will always erase data from its current logical
position and then write 300 frames of EOD. If this bit is set, an EOD is written to the end of the current partition.
