Hello Rudy and others,

RW> Update:

RW> I bought another sd card and again installed NOOBS v3.2.0 on it.

Be wise, stop using NOOBS,
that's for beginners and dummies who want to feel the first impression of
several OSes. NOOBS os not intended for intensive daily use by power users.
You are not a beginner anymore he?
Next time install Raspbian, and the current version is Buster 30 sept.2019.

This works on all Pi's, including the new 4B, but also all the old ones.

After unpacking and writing on a (micro-)SDcard, do:

# update installed packages
sudo apt-get update -y
sudo apt-get upgrade -y
# update your firmware
sudo BRANCH=next rpi-update
sudo apt-get dist-upgrade

Look here for instance:

Then you have an idea how to store a good shrinked (micro-)SDcard image,
as a backup for new trials on fresh cards.
Good luck

There was also a trick to not decompress the donwloaded SDcard image on a
storage media, but deflate it during writing to a fresh (micro-)SDcard,
in particular if the zip file is smaller than 4 GB, and the original
uncompressed image is bigger than 4 GB. The last one dows not fit on FAT.
For the last you need a medium wich can handle bigger files, like an ext4 Linux
 partition, but NOT the more often used and limited to max 4 GB files on a
FAT32 format of SDcards and USBsticks, because they can be used on more types
of OSes.
I.e. wirh FAT you have more exchange posibilities with other systems than
Linux.
The same happens with NTFS on Windows.

The unpack and write trick had to do something with piping I thought.
Unluckily I did not copy that article or trick to my DownLoad directory ;-(.
The other way round was also possible, i.e. get a diskimag from a real SDcard,
bigger than 4 GB and store it in a zip file during compression if you are sure
the total resulting zipfile wil be less than 4 GB.
Using that trick combine two handlings in one go, wihout storing the in between
 result in a bigger than 4 GB file on an EXT4 of NTFS meda.
Maybe I'll find these both combined backup and restore suring (un)zip
commands somewhere again?

Henri.
