Ok. Unchecking the "Mount removable media..." - second - option (don't know exact spelling, un-translating from my Spanish translation) in last version of gnome-volume-manager properties menu, while keeping "Mount removable devices..." checked, allows me to automount usbdisks while no automounting hard disk partitions.
This at the cost of not automounting CD / DVD disks (which really are removable media). I would suggest updating gnome-volume-manager/properties documentation to warn about this effect: local hard disk partitions are mounted/unmounted as if they were removable media. The term "removable" media is misleading in this case. Thanks for your support. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
