Upgraded firmware now won't sleep

I created a user-script file /CacheVolume that contains:

/etc/rc2.d/S85wdmcserverd stop
/etc/rc2.d/S86wdphotodbmergerd stop
/etc/rc2.d/S92wdnotifierd stop
/etc/rc2.d/S20winbind stop
/etc/rc2.d/S20minidlna stop
/etc/rc2.d/S85twonky stop
/etc/rc2.d/S50netatalk stop
/etc/rc2.d/S60mDNSResponder stop
/etc/rc2.d/S95wdAutoMount stop
/etc/rc2.d/S20nfs-common stop
/etc/rc2.d/S20nfs-kernel-server stop
/etc/rc2.d/S61upnp_nas stop

I found these entries in this post. Will that let this beast get some rest?

All I need it to do is hang out all day and wait for the 2:01 robocopy command to read the contents and copy what is necessary from my source drive. I do have an external USB drive connected to it. Should I remove any of the above lines to be able to use the USB?
