Hello, Mike! The problem comes from new version of UDisks - v.2 is not fully back-compatible with v.1. Udisks v.1 present in Ubuntu 12.04, Udisks v.2 present in Ubuntu 12.10+.
I contacted Udisks developer - David Zeuthen at https://bugs.freedesktop.org/show_bug.cgi?id=71802 , we have some progress. With latest commits Safely remove for USB-HDD is returned to Nautilus, but USB-flashes have only Eject. You can try to do Safely remove from Gnome Disks (gnome-disks command). It allows me to power-off USB-flash and USB-HDD. ** Bug watch added: freedesktop.org Bugzilla #71802 https://bugs.freedesktop.org/show_bug.cgi?id=71802 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1194608 Title: Safely remove does not work (LED is on) on USB 3.0 flash To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/udisks/+bug/1194608/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
