I would like to know how I can automount a volume placed on an external
USB port.

I am able to mount if I get root privileges, but the drive does not get
automount.

I have surfed the net searching for solutions and haven't found the
answer.

Thanks in advance.

That..... depends a lot on your distribution. Which Linux are you using, and
which operating system release?

It's possible with recent RedHat versions, for example, to allow users to
mount hard drives by setting specific settings in /etc/fstab. Auto-mounting
could be more of an adventure, depending on what the drives are and what
configurations you want them to have. And do you mean "mount at boot time",
or "mount and unmount it when I plug it in"?

Some details of what you're trying to do might help define what you need
better.

I try to mount it on FC4.

My idea is to keep the hard drive always plug to that machine.

The hard drive is a combo Seagate 300GB connected to the USB port.

I didn't manage to make it work using the firewire port. I tried the
drive in another machine using the Firewire port and works.

There is another question that comes to my mind.

this is the result of df -h

$ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
11G 8.9G 1.3G 88% /
/dev/hda1 99M 9.8M 84M 11% /boot
/dev/shm 252M 0 252M 0% /dev/shm
/dev/sda 276G 217M 261G 1% /mnt/external

When I come to fdisk I get quite confuse. Originally it was set the
mount as /dev/sda1. I don't know if this changed will make a big change
for futures update of the machine. Or in case I plug a second USB
drive.

Also the information about "mount and unmount it when I plug it in"
will be helpful as I won't need to reboot the system.

Once again, Thanks in advance.

it should have HAL. Nowadays autmounting is (usually) done by combination of
kernel + udev + HAL + user agent that does actual mount. I am surprised it
did not "just work".

Are you using GUI? Which one (KDE or Gnome and which version)? Do you have
HAL installed? Do you use udev?

That sounds like hardware issue unless another machine is using another
distribution.

This implies that either partition table on your hard drive was changed or a
bug in HAL or whatever software is used to setup mount points. HAL did have
some issues with FAT detection (are you using FAT BTW?)

http://freedesktop.org/ then got to Software and look for HAL.

Set "Enable Legacy USB support" in the BIOS - and ensure that 'USB' or
'Removable' device/drive appears (or atleast is not omitted) from your
Boot Order Device list in the BIOS...

System specs (CPU/Mobo/etc) may help, if above doesn't do it for ya

I had problems myself with external USB drives and FC4, at least out of the
box. I'd certainly update to the latest kernel: I was trying to use an
external 300 Gig drive as a mirror drive for a source code repository, and
it would hang with the default FC4 kernel. It got a lot better with 2.6.14
based recent kernels, but I never got a chance to really test it again under
serious load.

I wound up giving up on USB for the moment and switching to a firewire card
and the firewire port on the machine, which worked flawlessly.

Really: which kernel? And does a Knoppix boot CD or DVD detect it and mount
it properly?

It looks to me like someone set up the hard drive as a single filesystem
without ever setting up a parttion, this it mounts as /dev/sda instead of as
/dev/sda1. That.... could cause adventures. Can you type "fdisk -l /dev/sda"
and see what is reported?

Also looks like a good idea.
