[PROBLEM] HDD spin down not working

[javier.iba]

Hi,

I recently moved from alpha 5 to beta 1.1 and now, my HDD does not spin down (low power mode), never.

My device is Seagate 2TB Expansion Desktop (SRD00F2) with a Built-in Power Management system. It controls the HDD activity and spins down when idle, independantly of OS.

I post this thread after doing lots of tests, can anyone help me?

PS, sorry about my poor english

Thanks

Please try to add the parameter "nohdparm" to your cmdline.txt and reboot.

Thank you namtih.

That parameter was already included in cmdline.txt:
sdhci-bcm2708.sync_after_dma=0 dwc_otg.lpm_enable=0 console=tty1 root=LABEL=xbian-root-btrfs rootfsopts=subvol=root/@,noatime,compress=lzo,thread_pool=1,space_cache,autodefrag rootfstype=btrfs rootwait=10 smsc95xx.turbo_mode=N elevator=noop nohdparm splash logo.nologo quiet loglevel=0 noswap mod_scsi.scan=async

Do you think hdparm could be interfering in built-in power management system?

(I'm doing all the tests on a clean installation of Xbian beta 1.1)

Then I would try to remove the parameter from the cmdline.txt and see, if something changes. You can also check/edit the hdparm settings via the file "/etc/hdparm.conf" - especially the last lines.
