Coming back to this after some detours with the Ubuntu 18->20 upgrade still not
done...

So I have a box of 2.5" hdd drives, one of which turns out to be a 500GB ext4
with 11GB of data on it. I do not need that data, so it should be cleared away.
What is the best/quickest way to empty the drive? It attaches as sdd1.

Maybe when located in the top of the mounted file system:

user at ubuntuserv:/mnt/extdisk$ sudo rm -r /mnt/extdisk/*


Another question about rsbackup: 
Does it compress the data on the target backup drive?
