Since version 4.10, when kde started supporting udisks2 the option to safely remove a usb device doesnt work properly: it should umount and eject/shutdown the device, it works fine on a device that supports eject (like a card reader), but on a usb hdd that only supports power off, it just unmounts and thats it (the disks remains spinning, the led remains on, and i can remount if i want) Reproducible: Always Steps to Reproduce: 1. Plug a usb hdd and mount it 2. Use the option on dolphin or device notifier 3. A device with "CanEject: true" will behave properly, otherwise the device is umounted but not removed Actual Results: device still on Expected Results: device powered off the safely remove option on the device notifier has the same behavior, so the problem may be in kdelibs and not dolphin (sorry about that) i did "udisksctl dump" and it shows "CanPowerOff: true" so i dont think the problem is with udisks itself (i will do more tests and post the results here later)
Thanks for the bug report! (In reply to comment #0) > the problem may be in kdelibs and not dolphin You're probably right - I'll reassign to Solid, the part of kdelibs that handles this kind of interactions with devices for us.
I also found this bug is so important to fix. * What is expected to happen? External HDD spin itself down and turned off when ejected via device notifier applet. * What is actually happened? External HDD did not spin down and did not turn off. * Steps to reproduce problem: Attach an external USB harddisk. Click device notifier applet (the USB icon) on the KDE panel. Select the external HDD and click eject button. It says "click to safely remove the drive" on mouse hover. * Suggested temporary workaround to safely remove USB HDD Unmount all mounted partition on the external HDD via udisks (sudo udisks --unmount /dev/sdb1) Instruct udisks to detach the external HDD (sudo udisks --detach /dev/sdb) I hope kdelibs will be better integrated with udisks for mount, unmount, and detach operation.
