WRITE Command (0Ah) 4
The WRITE command transfers one or more data blocks from the host to
the current logical position on tape. When in Buffered Mode, which is the
default mode of operation, the DLT-S4 tape drive reports GOOD status
on
WRITE commands as soon as the requested data block or blocks have
been transferred to the data buffer. See MODE SELECT (6) / (10)
Command (15h / 55h) on page 98 for more information on Buffered
Mode.
