Question to HDD Spindown

[eselrob]

Hi,

i am new here in the Board.

I have a Network Space 2 with the original firmware V2.2.5. I have activated HDD Spindown after 15 minutes, but it work only for the internal HDD.

My question is, does the fvdw-sl-12-0 Firmware has a support for HDD-Spindown, internal-HDD and USB-HDD?

I have tested my external-HDD on a Fritzbox, there is the spindown working.

For the internal HDD there is a spin down function build in, but not for an external USB harddisk. Does a usb HDD, not spin down by themselves if not in use ?

[eselrob]

There are three types of external HDDs

Type 1:
Build-In Control with independent Power-Control (like Western Digital HDD)

Type 2:
Spindown is controlled by the connected System (most cheap cases)

Type 3:
HHD Spindown is not working

The Spindown funktion is integrated in the FritzBox from AVM and as well in the Freetz extension for the FritzBox (http://www.wehavemorefun.de/fritzbox/in ... E_SPINDOWN)

Do you think it is possible to implement this funktion in your firmware?

I have found the Freetz Spindown script here - http://www.heimpold.de/freetz/ - "spindown.sh"

thanks for this info , I will look into it and see if it is possible

I look at this and this scrips needs the sg3_utils command sg_start to stop the usb disk. I downloaded and compiled sg3_utils and the command indeed works on a usb disk I connected. So in principle all ingredients are there to put a spin down function of the usb disk into the firmware :mrgreen:

Is this subject regarded in the latest firmware? I tried sg_stop with putty but the command is not found. Would appreciate to get this function because my external USB disk also does not spindown on its own.

[fvdw]

O yes it is included but you should use sg_start (read the help text of the command) :mrgreen:
However no script is included to automatic spin down the usb disk, I forgot about it

Code: Select all

/usr/bin$ sg_start --help
Usage: sg_start [--eject] [--fl=FL] [--help] [--immed] [--load] [--loej]
                [--mod=PC_MOD] [--noflush] [--pc=PC] [--readonly]
                [--start] [--stop] [--verbose] [--version] DEVICE
  where:
    --eject|-e      stop unit then eject the medium
    --fl=FL|-f FL    format layer number (mmc5)
    --help|-h       print usage message then exit
    --immed|-i      device should return control after receiving cdb,
                    default action is to wait until action is complete
    --load|-l       load medium then start the unit
    --loej|-L       load or eject, corresponds to LOEJ bit in cdb;
                    load when START bit also set, else eject
    --mod=PC_MOD|-m PC_MOD    power condition modifier (def: 0) (sbc)
    --noflush|-n    no flush prior to operation that limits access (sbc)
    --pc=PC|-p PC    power condition: 0 (default) -> no power condition,
                    1 -> active, 2 -> idle, 3 -> standby, 5 -> sleep (mmc)
    --readonly|-r    open DEVICE read-only (def: read-write)
                     recommended if DEVICE is ATA disk
    --start|-s      start unit, corresponds to START bit in cdb,
                    default (START=1) if no other options given
    --stop|-S       stop unit (e.g. spin down disk)
    --verbose|-v    increase verbosity
    --version|-V    print version string then exit

    Example: 'sg_start --stop /dev/sdb'    stops unit
             'sg_start --eject /dev/scd0'  stops unit and ejects medium

Performs a SCSI START STOP UNIT command
