desktop icons for automounted external USB hard disks

Hello: TDE handles external USB hard drives the same as internal non-USB (ie SATA) drives. After plugging in an external USB hard drive it only places a device icon to the desktop if device icons for unmounted/mounted hard disks are enabled. I don't want to enable those icons because I have ~20 partitions I don't want to put on the desktop as devices. Still I would like to have removable USB hard disk icons on the desktop similarly to flash disks. How can I do it? In my opinion removable hard disk should be distinguished from internal non-removable drives in this context. Thanks, Istvan
