"Safely Remove" - Is Removing safely?

Link to this post 08 Jul 11

Hai
I have noticed just now that, when I try to remove my USB storage devices from system, in Slackware, using Safely Remove option, the LED in USB device continued its glow.

In my most of devices I dont have LED. When I used the old one I faced this. And for e.g, the USB device name is , NEW VOLUME means, that name is not disappearing from Main menu. If I click over it, again it is showing its content.

After I chose, Safely Remove, why still the device getting supply from system ? If I remove mean, that device wont get shock ? And if i click again means, contents are get displayed. So, what is the purpose of Safely Remove ?

I checked in my first distro, Fedora[laughlin] and my office system, SUSE, and W-----S XP . Things are fine, that is, after choose safely remove, LED get turned off and its entry is removed/disappeared from My computer window.

Why its not happening in Slackware ?

thanks.

I've never paid much attention to the "safely remove" stuff and I never had much of a problem, USBs are hot-swap-able regardless and do not get damaged, the only thing "Safely remove" does, as far as I know, is assure that its not currently in use when you pull it out.

to answer your question tho, I don't know.

The "Safely Remove" operation unmounts the disk so no further activity can be passed to it, it does not stop power from going to the device because the system and the USB drive still communicate to confirm that it is connected.

When you click back on the device it re-mounts the device.

I've noticed that "Safely Remove" will flush buffers to the usb stick and unmount it, but, if left in the slot and not removed, it will be remounted again. At least in Fedora. I will watch for the lights on the stick to finish flashing, and when I see the Dolphin window disappear, remove the stick before remounting takes place.

yes, I also had this experience. And I think its better . plugging out when it is getting power from system , is like, plugging/un-plugging the power chord to/from the power socket with the power switch is in ON condition. I remember, i read some where in my engineering curriculum, that this method is wrong. :(

So old fashion works great then, pull it out when your not using it, lol. Easy enough.
