I think, it is obvious that spindown capability depends on the hdd box's chipset only. So, I'll try to summarize the facts gathered:

Well, try to know which chipset is in the box before buing it. This page might help.

Hi,

regarding to USB enclosures with Cypress chipset, there might be a chance with following command:

/usr/local/sbin/scsi-start 0 --pc=2 /dev/scsi/host0/bus0/target0/lun0/disc

if someone has the knowledge how to program USB access, there is a special feature in the Cypress chips to pass-through ATA commands. Details are in the AT2LP rev C datasheet might be only a few lines of code for a pro....

also the chip has a register for setting autom. spindown value on ATA-initialisation, but I never got it to work....

Works perfectly for me, thanks!

I did some experimenting:

using my pc (ubuntu feisty fawn), I was not able to spin down the harddisk with the scsi-tools either (just as under kamikaze on a wl-500gP).

the lsusb output of the external HD is:
ID 04b4:6830 Cypress Semiconductor Corp. USB-2.0 IDE Adapter

Using the sg3-utils of ubuntu (http://sg.torque.net/sg/sg3_utils.html)
i did manage to make the disk spin down (but it didn't spin up until
after a reset of the drive)

I'm now trying to make a package out of it, but haven't finished yet.

[tuigje]

I just made an package, but sadly, it doesn´t work.

on my (ubuntu 7.04) pc, it works as expected:

sg_start --stop --pc=2 /dev/sda

On my wl-500gP however, it doesn´t:

sg_start --stop --pc=2 /dev/discs/disc1/disc
start stop unit: pass through os error: Invalid argument
START STOP UNIT command failed

I used the exact same source for both the PC and the WL-500G, both are statically build versions, so that´s not the difference.
On http://sg.torque.net/sg/sg3_utils.html it is noted that for kernel 2.4 the /dev/sg0 interface is required. It can be made with

mknod /dev/sg0 c 21 0

But I haven´t yet figured out how to enable the support in the kernel for /dev/sgX.
I can mount and read the disk, so scsi support itself is working fine.

I´m running kamikaze with 2.4 kernel (for wifi support) Is there anyone interested in testing this for kernel 2.6 ?
Both the makefile and (compressed) .ipk file are attached.

so, it was actually quite easy.

Here´s a small patch to kamikaze, which selects the generic
scsi driver as well.
The ipkg packge (for kamikaze 2.4) is included as well.

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

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

to make the devices and load the driver. Using:

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.

Guys,

After issuing the scsi-stop, I see that the HDD stops spinning but it starts again inmediately.
Does it means it's not working?

Thanks
