Prevent drives from going to sleep - Keep Alive
Some USB drives spin down after some idle time and then need a moment to answer on next access.
USBDLM can prevent the spin down by means of cyclic read accesses.
It is configured by means of [DiskKeepAlive] sections. Since it is related to disks and not to volumes, volume-specific criteria have no effect here.
Samples:
; read from all USB hard disks every 60 Seconds
[DiskKeepAlive]
DriveType=FIXED
Interval=60000
; read from a certain USB hard disk every 60 Seconds
[DiskKeepAlive]
DeviceID=USB\VID_0781&PID_5580\AA010319131128111123
Interval=60s
Default for the Interval is Null to make the Interval mandatory. Otherwise an empty section [DiskKeepAlive] would apply to all USB drives which would have been strange...
