I have marked that this bug affects me, but I have also somehow resolved this issue for my machine.
Steps I took which resulted in the bug: 1. Plug in new Western Digital My Passport Ultra into USB 3.0 port (running Ubuntu 12.04 LTS). 2. Use Disks utility to prepare for benchmark test. 3. Attempt to start benchmark, receive error. Steps I took between getting the error and not getting the error: 1. Unplug same Western Digital hard drive from USB 3.0 port. 2. Plug in same Western Digital hard drive into adjacent USB 2.0 port. 3. Use Disks utility to prepare for benchmark test. 4. Attempt to start benchmark. Success. 5. Plug in same Western Digital hard drive into previously used USB 3.0 port. 6. Use Disks utility to prepare for benchmark test. 7. Attempt to start benchmark. Success. I would like to believe something special happened when I plugged the hard drive into the USB 2.0 port that was not happening with the USB 3.0 port, however, maybe it was necessary that the hard drive go through an extra power cycle. Hope this helps. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-disk-utility in Ubuntu. https://bugs.launchpad.net/bugs/1236831 Title: Disks - benchmark pops error - Error opening /dev/sdb: Device or resource busy (udisks-error-quark, 0) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-disk-utility/+bug/1236831/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
