gnome's 'safely remove hardware' option[SOLVED]

Gome seems to do something when handling external hard-disks or usb-pens.
When using gnome (right-click on drive/disk image on desktop) and do a 'safely remove drive' on any mounted or even not mounted devices, these actually 'turn off'. My hard-disk spins down, and my usb-pen's little led goes out. Which is great, and the way it should be.

I'm now wondering what gnome 'actually does' there, and why/or if there is a way to incorporate this into other 'lightweight' DEs, or just a custom script for managing media.

Any ideas?

I believe gnome does that since gnome-disk-utility switched to devicekit-disks.
This might help you:
http://hal.freedesktop.org/docs/DeviceK … sks.1.html
Especially that looks useful

--detach  device_file [--detach-options options ]
   
Detaches (e.g. powering down the physical port the device is connected to) the device represented by device_file using a comma-separated list of options.

Ah, it's not simply an unmount? Have never noticed =p since I pull them out/manually switch them off anyway. It did not use to behave this way...

Re: gnome's 'safely remove hardware' option[SOLVED]

This was discussed a while back (I think .... can't find the thread) and I think someone even posted a script to do it from the cli, something like sumount (special umount) /dev/whatever and it would check if it was usb and if yes, unmount it and then power it off.

Re: gnome's 'safely remove hardware' option[SOLVED]

To power off my usb drive I use

#sdparm --command=stop /dev/sd[whatever]

after umounting.

...is it any different from the devicekit solution?

Re: gnome's 'safely remove hardware' option[SOLVED]

Hey, following worked for me:

devkit-disks --detach /dev/sdc

Thanks for the tip! I'm sorry for the late reply, but I got hit by a very lousy cold and was unable to respond Better now though...

@xenofungus, that code of yours does nothing
