This subcommand enables and disables the optional feature that causes the device to perform the set of off-line 
data collection activities that automatically collect attribute data in an off-line mode and then save this data to the 
device’s non-volatile memory. This subcommand may either cause the device automatically initiate or resume 
performance of its off-line data collection activities; or this command may cause the automatic off-line data 
collection feature to be disabled. 
 
A value of zero written by the host into the device’s Sector Count register before issuing this subcommand will 
cause the feature to be disabled. Disabling this feature does not preclude the device from saving attribute values 
to non-volatile memory during some other normal operation such as during a power-on or power-off sequence or 
during an error recovery sequence. 
 
A value of F8h written by the host into the device’s Sector Count register before issuing this command will cause 
this feature to be enabled. Any other non-zero value written by the host into this register before issuing this 
subcommand is vendor specific.   
 
Automatic off-line data collection is executed every 24 power-on hours.
