[Bug 1236831] Re: Disks - benchmark pops error - Error opening /dev/sdb: Device or resource busy (udisks-error-quark, 0)

 

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.

Title:
  Disks - benchmark pops error - Error opening /dev/sdb: Device or
  resource busy (udisks-error-quark, 0)

Status in gnome-disk-utility package in Ubuntu:
  Confirmed

Bug description:
  There are many errors in working with USB (creating USB startup disk
  was the first to see) and now I cannot benchmark the USB drive as I
  get the Error opening /dev/sdb: Device or resource busy (udisks-error-
  quark, 0) error. I tried dozen of times, to make sure it is not
  something temporary. At some point I could do it on a different thumb
  drive, I do no know how, but after 2 errors, it worked. The second
  thumb drive was not that lucky.

  There is some other bug, the one that I used before still appears in
  the list, see screenshot. It is not connected, but appears in Disks
  application drives list.
