I have a strange problem with usb drives on lubuntu12.04. When I plug a usb drive into a pc with lubuntu installed and look at the content, then remove it and modify its content in another machine then plug it back into the lubuntu machine, the change does not seem to be picked up by the gui.
For example, if I plugin the drive, open it and then remove the drive, and plug it into a different machine and remove some files, then plug it in again into the first machine (with Lubuntu) and open it with pcmanfm the files' icons are still showing even though checking in the terminal confirms that they have indeed been deleted.
Or, I plug a usb into a lubuntu machine, open it and inspect its content, then remove it and plug it into a different machine to add some files. When plugging back into the lubuntu machine and open the drive with PCmanfm these files don't show up, yet checking with the terminal confirms that these files are present.
So it seems that when the usb drive is first plugged into lubuntu, it somehow remembers what is in it and that if the drive is modified later in a different machine, the changes don't get picked up by pcmanfm when the same drive is plugged into the original lubuntu machine a second time.
Sorry if it sounds a bit confusing, but it seems to be a very confusing problem. Does anyone experience the same problem?
Thanks for any suggestion or advice.
