Well & OK, this I already understood ! ;-)

Absolutely correct and that's why I label them with unique
identification ! ;-)

It's not "don't or won't !! ;-))

I am in the process of learning how to setup my Linux environment.
I believe to know what I want but currently I lack of fond experience
and knowledge 
to reach it accordingly.

You are correct: UUID's are unique like my (unique) Disk Labels.
Hence I have to learn and recognize what the system really needs and 
how the system controls it !?

I need to understand how it works and have to learn it accordingly.
 

There is, especially with these more and more USB devices connected,
another problem:
The easy and dynamic exchange of i.e. USB sticks used on and off in
these USB hubs !!!

I am using a Hama Traveldrive 1000 & 1, USB 2.0 Multi-/Dual-Card Reader
http://www.hama.de/portal/articleId*127948/action*2563

Like this all USB media units (external HDD or the sticks) are plugged
on when needed and removed after things are done ! The system has to get
along with this and it works only if I do/did it properly.

This has been done yesterday already after Derek suggested it. ;-)
Exactly this has brought the two icons (LD142ext3 & LD142ntfs) visible
under Places/Computer. ;-))

Thanks again ! 
I will give a try / some tries this weekend ;-))

I appreciate every feedback on learning to get my problem solved and
only hope: 
I do not get an unsolvable disaster ! ;-D

Once again thanks for all your efforts.
Cheers, svobi
