Thanks to all those who have responded. I think that I now have a pretty fair idea of the way Linux today assigns device labels. Also, when I re-booted after updating my system, the file browser dropped the ghosts and found the new SATA drive OK, so that problem went away.

Once again, thanks to all who responded.

Up until a couple of days ago, I had 3 EIDE drives and POST reported my hard drives:

    IDE Channel 0 Master     a 120 GB drive
    IDE Channel 0 Slave       a 120 GB drive
    IDE Channel 1 Master     a 160 GB drive
    IDE Channel 1 Slave        a DVD
    IDE Channel 2 Master     None
    IDE Channel 3 Master     None

Simplifying things, channel 0 Master has my Windows Installation, Channel 0 Slave my Linux stuff, and Channel 1 Master is a backup/clone of Channel 0 Master. Ubuntu sees the three drives as sda, sdb, and sdc.

Monday I picked up a couple of 1.0 TB  SATA drives. Starting slowly, I added one to Channel 2. I cloned the Windows drive (Channel 0 Master) to it, pulled the power plug on Channel 0 Master, and changed the boot sequence in Setup. I also changed the label on one of the partitions on the new drive. POST reports:

    IDE Channel 0 Master     None
    IDE Channel 0 Slave       a 120 GB drive
    IDE Channel 1 Master     a 160 GB drive
    IDE Channel 1 Slave       a  DVD
    IDE Channel 2 Master     a SATA 1 TB drive
    IDE Channel 3 Master     None

Windows works pretty much OK. Booting into Ubuntu 9.04, I was surprised that Gnome's File Browser shows ghosts of the old channel 0 Master--complete with the labels of the old partitions, and does not show the new drive. I brought up Gnome's gparted. It saw the new drive just fine--as sda! I had expected almost anything--except sda. This is not a "real work" Linux installation and besides, /home is in a different partition, so I could just re-install and that would probably fix things, but I'd rather make what's there work correctly.

Questions:
    1) Why did a SATA drive on Channel 3 show up as sda?
    2) How can I kick Gnome's File Browser into dropping the ghosts and showing the contents of the new drive?

I guess that all of my admin/reference books are out of date, because I can't find anything in them that helps. The MAN pages would probably help, but I don't know where to start.

Any help, pointers to where I can find explanations, etc. will be much appreciated.

Thanks,

Mark Jarvis
