7.4 Background Media Scan (BMS)
C141-C013 399
EN_BMS (Enable Background Media Scan)
When this bit is set to "1," the Background Media Scan (BMS) function is
enabled. Media scan processing will begin at the time determined by the
BMS Interval Time (bytes 6-7) specification.
When this bit is cleared to "0," the BMS function is disabled. Clearing this
bit to "0" while BMS media scan processing is in progress immediately
suspends the media scan processing. Setting the bit back to "1" immediately
resumes media scanning from the point of suspension.
EN_PS (Enable Pre-Scan)
When this bit is set to "1," the Pre-Scan function is enabled. Clearing this bit
to "0" while Pre-Scan processing is in progress immediately suspends the
scanning processing.
BMS Interval Time
Once Background Media Scan (including Pre-Scan) processing is started, the
next Background Media Scan operation will begin after the time in hours
specified in this field. When '0' is assigned to this field, the minimum value
of '1' will be reported.
Pre-Scan Timeout Value
When the time in hours specified here elapses, Pre-Scan scanning processing
ends, assuming a timeout.
Minimum IDLE TIME before Background Scan
Displays the time from IDLE status to start of BMS (unit: milliseconds).
HDD ignors the values specified for this parameter and operates in
accordance with the default value.
Maximum TIME to suspend Background Scan
Displays the maximum amount of time required until the execution of a
command (unit: milliseconds) when a command is received during BMS
operation. HDD ignores the value specified for this parameter and operates
in accordance with the default value.
