Try sizing it/setting it the way you like to view it, click on the silver oval in the upper right corner to shrink up the favorites bar, then close the window. Then double click on the drive to reopen the window and click on the silver oval again to reopen the favorites bar. If you close the window again, it should reopen as you left it. I know it's screwy, but that's the way it's worked in OS X for several versions now.
