Exteran USB HDD is not pwoered down on "Safely remove" action When clicking "Safely remove" icon near mounted drive, that disk is unmounted, but is not powered down. I can feel it virating (spinning), and unpluging it makes... bad sounds. Reproducible: Always Steps to Reproduce: 1. Attach external drive 2. Mount it as suggested, open Dolphin. 3. Open mounted drive's context menu, click "Safely remove..." Actual Results: Drive is unmounted, but not powerd down (drie is still spinning). Expected Results: Drive sould be powered down. I'm using Kubuntu 14.04.1 amd64. There is no such problem in Xubuntu 14.04 and Ubuntu 14.04. I've tried all tree variants in clean LiveCDs. Kubuntu (Dolphin/KDE/?) is one of them that does not spin down my exteran drive. At first this problem was the same in Ubuntu I've used earier, bug mentioned here: https://bugs.launchpad.net/gentoo/+source/nautilus/+bug/1067876 . But looks like only Kubuntu/KDE has this problem left, at least with my drive: Bus 002 Device 008: ID 152d:2329 JMicron Technology Corp. / JMicron USA Technology Corp.

It does spin down if I use "sudo udisks --detach /dev/sdX" after unmounting.
Thanks for the very detailed bug report! Dolphin uses Solid for mounting/unmounting storage devices, so I'll reassign it to Solid.
*** This bug has been marked as a duplicate of bug 270808 ***
I do quite a bit of work with an external hard drive, so I am quite disappointed that the duplicated bug has marked this as a won't fix. This means that I will have to always unmount and use udisks to detach the external hard drive. Actually, this bug has made me hesitant to recommend KDE to other users, since I do not want to be responsible for anything that may cause a malfunction in other users' external drives. Even if it does not cause a malfunction, I do not want to cause other users to worry, especially if they come from a Windows environment. To any KDE developer reading this, I humbly ask him or her to implement this feature, even if it is just disabled by default. I would truly appreciate it. Thank you.

Thank you. If you read all comments in bug 270808, you will see that a fix has already been developed by the people working on Solid (this is the library which is responsible for interacting with devices). They just decided not to apply the fix because they felt that it needs more testing to reduce the risk of regressions, and nobody volunteered to test it. It seems that you would appreciate to see this fix in the next version of Solid, so it would be great if you could get in touch with the developers (just add a comment in bug 270808 or e-mail them) and ask them what you can do to help with testing. I'm pretty sure that many KDE users will be grateful! Thanks for your help.
