When I open the Gtk file dialog, there is a box called “Places” on the left-hand side which lists “Search”, “Recently Used”, a bunch of directories, and several things that appear to be volumes. I don't care about any of these entries, but for the most part I don't mind, except for one.
One of the volumes is on an external hard disk that spends most of its time spun down. Opening the Gtk file dialog makes this disk wake up (presumably because the application reads the disk size or label and that information isn't in the cache). I want this to stop.
etch200808 is the label of a mounted filesystem. I have two 500MB filesystems mounted, one of them is on the external disk that I don't want to spin up. I'm not sure what the 412 GB one is: I have no filesystem anywhere near this size; I do have an LVM physical volume that's the right size. I have no idea why these are displayed and not any other volume of various types on this system.
How can I force this volume (or all volume, or all directories) off the “Places” box? Note that this isn't just about not being listed, this is about the mount point not being accessed, so that my disk doesn't spin up just because I wanted to open or save a file from a Gtk application.
I'm running Debian wheezy, but I want to know the answer for other distributions and generations as well — if only because this machine will be upgraded to jessie soon.
