HD permissions stay put

[Johan Scheepers]

Good day,

I have a multiple boot internal drive (different linux 
flavors)(excluding windows).

Have a external usb drive for backup between these different systems.

Now booting in a different flavor the permissions change to numbers.

My normal permission is johan johan. I am the only user at home.

It is auto boot if from boot or later.

Now as root  I change the owner and group -R.
This is annoying . Is there a way to make it stick please.
Thanks
Johan S
