I would have expected sdd or sde or something like that.

Where can I find info on tweaking Ubuntu's HD recognition?

This is a normal condition.

As far as the "ghosting" showing up in Gnome's File Browser I have no clue.

Subject: SATA drive problem


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I guess that all of my admin/reference books are out of date, because I can't find anything in them that helps.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
