I have an external drive I set up yesterday that has the name
"a3cd7e7f-254d-410a-b120-e02524f75a29." How can I change that to
something like "/run/media/bobg/externaldrive?"

What type of file system? If you're using ext you can label the file system with
e2label
and it should come up mounted with the label name. If I'm not mistaken.

Thanks Ed, that seems to have worked although I'm don't understand how ...
[root@Box10 ~]# mount /dev/sde1 /mnt/temp/
Mounts the drive to /mnt/temp/ and "mount" shows the following:
[root@Box10 ~]# mount
............ snip ............
/dev/sdd1 on /mnt/temp type ext4 (rw,relatime,seclabel,data=ordered)
/dev/sde1 on /run/media/bobg/st1000 type ext4
(rw,nosuid,nodev,relatime,seclabel,data=ordered,uhelper=udisks2)
/dev/sde1 on /mnt/temp type ext4 (rw,relatime,seclabel,data=ordered)
It does what I asked!

If a removable device has a label, the system will create a mountpoint
for it using that label; it was using the UUID simply because that was
the only unique identifier it had.

The curious thing is I did: # e2label /dev/sdd1 st1000
and now, from mount, I see three devices:
/dev/sdd1 on /mnt/temp type ext4 (rw,relatime,seclabel,data=ordered)
/dev/sde1 on /mnt/temp type ext4 (rw,relatime,seclabel,data=ordered)
/dev/sdf1 on /run/media/bobg/a3cd7e7f-254d-410a-b120-e02524f75a29 type
ext4 (rw,nosuid,nodev,relatime,seclabel,data=ordered,uhelper=udisks2)
It works just fine, puts an icon on the desktop and I can mount it from
that.

Allegedly, on or about 24 July 2016, Bob Goodwin sent:
/dev/sdd1 on /mnt/temp type ext4 (rw,relatime,seclabel,data=ordered)
/dev/sde1 on /mnt/temp type ext4 (rw,relatime,seclabel,data=ordered)
You've mounted two things onto the same mount point. Do-able, but the
second thing takes over, and the first one becomes hidden. You should
really unmount something before mounting something else over the top of
it.
If you've been unplugging and replugging USB drives rather quickly, even
if it was unmounted, the system doesn't let go of the previous device
name (e.g. /dev/sdd1) immediately, and when replugged it may be given
the next available device name (e.g. /dev/sde1).
If you unplug, wait some time, then replug, chances are that the
previous device will be noticed as free, and the second time its loaded
up, will be given the same device name as before.
Ordinarily, it probably doesn't matter that something has changed device
names, as we're supposed to be using labels and unique IDs to refer to
drives. But it can be confusing when trying to sort out hardware, and a
potential risk if your next task was to do something with a device based
on the device name. You end up operating on the wrong thing.

OK.... But please note.

It does what I asked!
You seem to have /dev/sdd1 already mounted on /mnt/temp.
And you've manually mounted /dev/sde1 on /mnt/temp as well as it being automounted on
/run/media/bobg.
Not sure that is what you wanted to accomplish.

After boot this morning I switched on the power on the external, usb
drive adapter and an icon appeared on the desktop screen. I clicked on
"Mount" and got:

So the command 'e2label /dev/sdd1 st1000' makes it possible to add
another device, it doesn't change the name. What did I miss in setting
up the external drive initially?
None of this really matters since all I need is to have the data saved
and to be able to use it to recover if needed. But I would like things
to work predictably whan I configure something.

Two questions: first, have you rebooted, or otherwise
unmounted/remounted that drive since giving it a label and second, what
does 'e2label /dev/sdd1' return?

Yes I ran the command yesterday and have re-booted several times since,
usually shut this computer down at night.
[bobg@Box10 ~]$ e2label /dev/sdd1

It shouldn't make any difference but I just realized that when I label my file systems
I
didn't use e2label but I used tune2fs.

That's what I thought after reading through the man page, but thought I

IIRC, yesterday you were labelling /dev/sde1, not sdd1.
Did it get enumerated differently today?
If the system consistently mounts the drive to a specific
location (ex /run/media/bobg/<UUID> you could make a
symbolic link to the mount point in your homedir,
say /home/bobg/extdisc. If the drive is mounted you
have an easy to use path to it. Otherwise it will
just be a broken link, no problem.

Yes, I apparently had it mounted as several devices but normally it is
/dev/sdd1.
Your suggestion is interesting but I don't think I need that. I have a
Samba server set up as raid0 that I want to make changes to [eliminate
the raid] and just needed a place to back up ~ 239GB of data, mostly
image files. Once that is done my need for an external drive drops to
virtually nothing. It's not to be accessed often, hopefully just once.
