Thanks to all of you who have tried to help.
Unfortunately, I am still lost.

I just want to run Gentoo on my system, and the new drive is just for  
backup, i.e. it needn't be bootable.

I have zeroed the first 8 MB and then I used gdisk
gdisk still notes that there is a backup GPT. I opted to created a new  
blank GPT.
Then I created 4 partitions.
I have used the w(rite) command before exiting gdisk.
Starting gdisk again, it shows the 4 partitions.
But, after a 'sync' command I detached and re-attached the drive and I  
get partially strange
output from dmesg :

and only  /dev/sde and /dev/sde1 are visible.

Where are the other partitions - or am I missing a kernel option.
That is my first drive bigger than 3 TB.

Many thanks for your help,
Helmut
