Keep Alive

USBDLM

 

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...
