Use this patch to make the scsi-kmod module, then do a

Code:

mknod /dev/sg0 c 21 0
mknod /dev/sg1 c 21 1
insmod sg

to make the devices and load the driver. Using:

Code:

sg_start -s -p 2 /dev/sg1

you can now spin down a scsi device. The scsi-start utility still doesn´t
work for me though.

How can I install "scsi.patch"?
I tried to install "kmod-scsi-core_2.4.34-brcm-1_mipsel.ipk" in your "scsi.tgz" and then I got an error message: ...md5sum mismatch...!
How can I countinue? Thanks

MMm, I wouldn't know were ipkg gets the md5sum from. the md5sum
in the Makefile is correct, i just checked that.

Building from source should work. I'm now running a 2.6 kernel, that
already has proper scsi support, that might work
for you also (but 2.6 still no wireless AP-mode for the wl500g).

Kamikaze brcm47xx kernel 2.6 on Asus WL-500gP

USB -> SATA adapter is a very cheap one, but based on Sunplus:

Code:

# cat /proc/scsi/usb-storage/0
   Host scsi0: usb-storage
       Vendor: Sunplus Technology Co.,Ltd.
      Product: USB to Serial-ATA bridge
Serial Number: FDF724040F000000FFFF2CFAFFFA9D
     Protocol: Transparent SCSI
    Transport: Bulk
       Quirks:

Code:

# cat /proc/bus/usb/devices
Vendor=04fc ProdID=0c25 Rev= 1.12
Manufacturer=Sunplus Technology Co.,Ltd.
Product=USB to Serial-ATA bridge

So from all I can read it should be working, but when I run scsi-stop I get:

Code:

# /scsi-stop /dev/sda
/dev/sda is not a SCSI block device

or a different program I found here: http://www.johnkerry.plus.com/scsi-spin.html which should be compiled for Kamikaze (no version mentioned) and kernel 2.6:

Code:

# scsi-spin -d -f /dev/sda
scsi-spin [warning]: device is mounted but --force is passed
scsi-spin: /dev/sda is not a disk or generic SCSI device.

Anybody have any ideea why it is not working?

The harddrive is a Hitachi 400GB SATA U150: HDS724040KLSA80

$ cat /proc/scsi/usb-storage-1/1

I explicitely checked the 500GB and the 750GB version.

I'm a total Linux newbie but still I managed to spin down my HDD with scsi-stop. I also put scsi-stop.sh script in my router according to instruction provided here. However two questions come to my mind.
Is this instruction full or do I have to do something more to get this script running every time I reboot my router?
I read here that it is impossible to spin-down HDD when Samba is running. Is it true? I am using my HDD as a media disk so everyone in the house can acces it. That is why I don't want to use the switch on the enclosure to power off/on my drive (it won't be accessible). I want it to be accessible all the time but to spin-down in periods of inactivity (e.g. when everone is at work, at night) to extend life of the disk and not to make noise in the night. I use Samba to share disk in Windows.
As I'm new to Asus's router and Linux any help will be apreciated.

I found the following deamon:

Spindown is a system daemon that spins down idle disks [...] uses sg_start to spin the disk down. It also works with usb disks and hotswappable disks because it doesn't watch the device name (hda, sdb, ...), but the device id. This means that it doesn't matter if the disk is swapped while the deamon is running.

Searching the internet on one of the bridges, I came across this site:
http://www.hdsentinel.com/usbharddisks.php
These might all be working bridges?!
Checking the list with the known good list here, I think it doesn't give any guarantee.
