Public bug reported:
When I plug in my USB disk it is detected as 2 disks in Ubuntu 10.10.
This was not an issue with 10.04. Also after plugging in the USB disk it
takes a long time for the drive to mount. The device detected as sdb is
the correct one. I have also tried to mount this disk with 10.04 live
and it was fine.
Currently I have a fresh install of Ubuntu 10.10 where I am facing this
bug.
dmesg output is as follows:
