eSATA hotplug not working well with Nautilus

Hi,
I have an external eSATA disk I use for backups.
I am using it with several machines, including two ubuntu-9.04 Jaunty, fully updated, machines.
Behavior on both is very similar.
The following concerns an Acer Aspire 8930 installation.

I am fully able to use it from the command line, so I'm reasonably happy ;)
Problem is Nautilus is working just half-way:
If I power-up with the disk attached it *is* recognized and Nautilus *does* know it is a removable disk because it shows the "umount" buttons beside its mount-points (under /media).
I can detach the disk just clicking on them and then detaching the drive.
At this point (correctly) the partitions disappear from the [Places] menu. If I have an open window on "Computer" the icons do *not* automagically disappear, even after refresh; I don't know if it's significant. Any subsequent opening of "Computer" does not show the (now unavailable) partitions.
So far, so good.

Problem is if I reattach the drive (or attach it after boot) nothing is displayed anymore in Nautilus.

The system detects There is a new disk:

The eSATA drive is /dev/sdb.

They are, however, visible neither in [Places] nor in "Computer".
I can mount the partitions manually, but they will *not* be under /media and they will not look as detachable.

I submitted this same message as "Question" and I was redirected here, so here I am :)

I am available to provide any further info required.
