Comment 16 for bug 469837

Hi! Sorry again, this is a slow bug report, huh? :P

I think I started same as before:
Booted and started Launchpad in Firefox (and changed always wrong LiveCD system time :P)
Started Gparted and didn't make any partition/drive changes and then closed it. Places menu now shows all partitions.

Here, I did a little bit different (kind of lazy to wait for re-login and wondered if it would be same anyway):
This time, I didn't log out, but instead plugged in a 2GB flash drive, which showed up fine.
Then, started Gparted 2nd time and again didn't make any changes.
Closed Gparted.
Not sure if Places menu changed after open or after close of Gparted the 2nd time, but anyway, it's now empty except for flash drive and Vista's C drive.

I then tried the command you gave:
  sudo udevadm trigger --action=change --subsystem-match=block
It just went back to the prompt right away and didn't give any message, and Places menu didn't change.

I tried it a couple more times and still nothing. I think this was all with the 2GB flash drive also still plugged in.

As I was writing this, I copy/pasted your command back in and also left my computer for a few minutes and when I came back, Places menu was normal, except it said the 2GB flash drive was "Unrecognized" and it couldn't unmount it. I plugged it back in and had no response for a few minutes, unplugged and tried again, and that made the Places menu show nothing again (except flash drive and Vista drive.)

I tried the command several more times and also ran Gparted, but it didn't happen again yet.

This is kind of confusing to me, but I feel maybe it's caused by plugging in the flash drive instead of relogging in...

Hope I didn't make it too confusing..^^;;; and I hope it's useful.
Thanks again~ (And thanks, I'll try System Testing soon!)
