HOWTO: Disable WD IDLE3 via ReadyNAS

I ended up using the advice here (http://blog.vacs.fr/?post/2009/03/21/Co ... ing-SSH%3A) and here (http://readynasxtras.com/forum/viewtopic.php?f=5&t=27) to get started. I used the free telnet client program called PuTTY (http://www.putty.org) to make the interface between my Win7 x64 computer and the ReadyNAS Ultra 4.

SYNTAX (from the idle3 Sourcefourge page http://idle3-tools.sourceforge.net/)

idle3ctl [options] /dev/device
•-h : display help
•-l : show license and exit immediately
•-V : show version and exit immediately
•-v : verbose output
•--force : force even if no Western Digital HDD are detected
•-g : get raw idle3 timer value (default action)
•-g100 : get idle3 timer value as wdidle3 v1.00 would display it
•-g103 : get idle3 timer value as wdidle3 v1.03/v1.05 would display it
•-d : disable idle3 timer
•-s<value> : set idle3 timer raw value (1-255)

I used the command ./idle3ctl -s145 /dev/sda which resulted in a 510 second timer. I confirmed that with the command ./idle3ctl -g103 /dev/sda.

I'm really not sure yet how the different version of wdidle3 affect the timer raw value, but at least I'm getting started on understanding. One of my drives had a LCC of 286,000, so I needed to do something quick.
