Ubuntu 20.04.1 Using Mate desktop. External USB drive WD 1TB /dev/sdc
Have spent at least four hours trying to give permissions to this external drive I'll be using for back up and have failed with every attempt.
Drive was formatted with Gparted using ext4. I can mount it in FILES and it shows a blank white screen. I can rgt click inside that and it gives me all sorts of options and I've tried them all trying to Paste any folder or files inside...and Paste is always grayed out.
I've tried sudo chmod -R a+rx (and uppercase X too) /dev/sdc and several other Term commands trying to get it to allow me to use it as a Bkup drive without success.
I've opened Permissions with a rgt click in that drive and no matter what command I've tried, in Root, or Term, afterwards in permissions it always shows me 'You are not the owner, so you cannot change these permissions."
Yes, I've tried several 'Change ownership' commands after searches but most of the instructions are from years ago.
