you are right, I'm not on Debian 8.1, I'm on 8.7.
I'didn't know about permissions for ntfs and fat, it does make a bit more sense.GarryRicketson
, I know about chown and chmod, and I usually use chown to change usb permissions for current user.
I know that "to use /dev" you need to be root, but I'm sure that before it wasn't needed to change permissions after formatting with gparted. And gparted always needed to be start as super user.
maaaah... I'll do some command line to change the permissions.
But still,...when you launch gparted (or any other app) from activities, I don't think it is "normal" that you should go to command line to finish whatever has been done.
Anyway thanks guys
