Prerequisites

To complete this guide, the following is assumed:

You are running Oleg's firmware (1.9.2.7-6b or later)

You have harddisk partitions up and running with an extended filesystem mounted to /opt

You have installed the Ipkg package system.

You have configured your partitions to automount.

You are using an IDE Hard Disk inside the WL-HDD enclosure (for USB Hard Disk connected to a 'WL500G' you can use scsi-stop, see this thread.)

This package will allow you to place your harddrive in a standby-mode.

Install the Package

First we need to install the hdparm IPKG package.

  ipkg install hdparm

the result should look like this ...

  #Installing hdparm (6.1-1) to root...
  #Downloading http://ipkg.nslu2-linux.org/feeds/unslung/wl500g/hdparm_6.1-1_mipsel.ipk
  #Configuring hdparm
  #Successfully terminated.

If you have the standard partition setup on the WL-HDD (from following the wiki) then you should enter the following into the shell:

  hdparm -S 120 /dev/discs/disc0/part1
  hdparm -S 120 /dev/discs/disc0/part2

This will send your primary and swap partitions to sleep.

If you have any other partitions (3, 4 etc), it is necessary to enter the following replacing # with the partition number.

hdparm -S 120 /dev/discs/disc0/part#

and the result should look like this ...

  #/dev/discs/disc0/part1:
  #setting standby to 120 (10 minutes)

If you do not want to loose these settings after reboot ...

  nano /usr/local/sbin/post-boot < enter >

and insert at the bottom ...

  sleep 60
  # Set Standby of internal HDD to 10 minutes
  /opt/sbin/hdparm -S 120 /dev/discs/disc0/part1
  /opt/sbin/hdparm -S 120 /dev/discs/disc0/part2
  /opt/sbin/hdparm -S 120 /dev/discs/disc0/part# (only if you have other partitions)

into to your post-boot script and finally save it to the flash ...

  flashfs save
  flashfs commit
  flashfs enable
  reboot

---

Thanks to the contributor of this guide (I did not write this one). I have set it up on my WL-HDD and it works brilliantly.
