[Trisquel-users] Need root permission to read/write disk after formating it, how to set it up so as it is not needed?

Following the wiki guide  
https://trisquel.info/en/wiki/how-format-external-storage-device-using-parted

When all is done I need root permission to read/write the disk. Is it  
something I can do so root is not needed to read/write disk?
