"Safely Remove" - Is Removing safely?
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.

to answer your question tho, I don't know.
When you click back on the device it re-mounts the device.
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.
Friendly advise: get ready to lose your documents any random day.
Don't *EVER* do that!!!! the "safely remove" (as the other have said) unmounts the filesystems and flush the information that was to be written to the device.
As for the OP... it probably is just the energy supply

That method is definitely wrong, I learned that the hard way when USB jump drives were first sold by destroying two USB devices when I unplugged them without them being in the safe state.

I am almost sure, there is no input source inside USB devices [pen drives] , so it is getting power/energy supply from system.
So, again, is this method is correct ?
wait for lights to stop flashing
wait for dophin window to close
Somehow I guess I didn't make myself clear.
It may be flashing because of some extra communication to confirm that the device is still connected, once it states that it is safely removed the umount is complete so you can consider it safe to remove from your computer.
Edit: Interesting, I think that in Fedora KDE the problem is fixed. It's not remounting itself. I bet anything that is was the Gnome 2 DE in Fedora 14 that was causing the problem (Or maybe it was just Fedora 14). So, since I started running Fedora 15, I've been rushing to remove the usb stick before it remounted, and, I didn't have to. I'm glad I found this out.
So,you are concluding this as a problem . Whatever, but I afraid when my data will lose as Marc mentioned .
Hope , that LED glowing won't give any problem.
