I'm facing the same problem so I will gladly provide you with additional information if required. ** Bug watch added: freedesktop.org Bugzilla #79184 https://bugs.freedesktop.org/show_bug.cgi?id=79184 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to udisks2 in Ubuntu. https://bugs.launchpad.net/bugs/1516288 Title: keeps showing disks that aren 't connected any more Status in udisks2 package in Ubuntu: Incomplete Bug description: I have a usb stick that got corrupted by usb-creator (which errored while erasing it). Obviously, no matter how corrupt the content of the usb stick, Disks must allow me to at least format it as long as the hardware is fine. I first opened Disks, and it showed TWO items related to the usb stick: - Toshiba TransMemory (without any /dev/something) - Generic USB Mass Storage ( /dev/sdb). The "Format" option was greyed out for both. I unplugged the drive. Then I restarted Disks, and it still shows "Toshiba TransMemory", though the stick is not even plugged in.
