[Ipodlinux-devel] Powersaving with hdparm

[Jonathan C. R. <jon...@ba...>]

Hi all,

I have just 'ported' hdparm to my iPod, and added the following line to
my /etc/rc:

   hdparm -S 1 /dev/ide/host0/bus0/target0/lun0/disc

now my harddisk spins down after 5 seconds of inactivity, and spins up
again quite happily when needed.  I will do some tests over the next
couple of days to see how long the battery lasts in various
circumstances - perhaps 10 seconds spindown will prove better.

The patch is quite simple, just affecting the Makefile: 

$ diff hdparm-5.5/Makefile.orig hdparm-5.5/Makefile
13c13
< CC = gcc
---
> CC = arm-elf-gcc
17c17
< LDFLAGS = -s
---
> LDFLAGS = -s -elf2flt

Cheers,
	Jonathan.
