Force Verify
A Force Verify bit of 1 indicates all write operations are
verified. The Write 6-, 10-, and 12-byte commands
operate as if they were Write Verify 6-, 10-, and 12-byte
commands.
A Force Verify bit of 0 indicates normal operation.
Bytes 4 and 5
Bytes 4 and 5 are used to read the setting of the DIP
switches on the drive. SX-Y refers to the setting of DIP
switch S50X-Y (see Figure 2-1 on page 2-51 and
Table 2-44 on page 2-51). If SX-Y=0, the switch is set to
the OFF position; if SX-Y=1, the switch is set to the ON
position. These fields are not changeable. The switch
setting value overrides the saved value.
DOM
A drive operating mode of 0 indicates that the drive is
installed in a jukebox environment. A DOM bit of 1
indicates that the drive is installed in a stand-alone
environment.
NOTE
The DOM bit is not selectable using the Mode Select command.
FWC
A Force Write Calibration bit of 1 instructs the drive to
perform the Write Calibration routine at spin-up. A
Force Write Calibration bit of 0 instructs the drive to
perform the Write Calibration routine on receipt of the
first Write command or 5 minutes after spin-up.
NOTE
The bits DAIR and Force Verify on this mode page can also be controlled
in HP products by changing external switch settings. In HP’s standalone
box products, this is accomplished by changing the thumb wheel settings
on the rear of the box. In HP’s library products, this is accomplished by
changing the front panel settings. In all cases, changes to the mode page
settings will override the external switch settings.
